Sandy soils RG.pptx
Sandy soils are formed from the breakdown of rocks like granite and limestone. They are characterized by large sand particles that do not stick together well, giving sandy soils low water and nutrient holding capacities. Management of sandy soils focuses on improving structure and moisture retention through organic matter additions, cover cropping, and mulching. Irrigation scheduling is also important for sandy soils to minimize leaching and maximize crop water availability. A case study in Norway found that ancient sandy terraces showed evidence through radiocarbon dating and soil analysis of anthropogenic soil improvement and cultivation, indicating sandy soils have been managed for agriculture for over 1500 years.

A brief description about soil genesis formation, pedology and edaphology concept, solum and regolith, soil pH and soil profile for the Engineering student at Under Graduate level
Soil and its types
Soil is a complex natural body that forms at the interface between the earth's atmosphere, biosphere, hydrosphere and lithosphere. It is composed of weathered rocks and decaying organic matter and provides a medium for plant growth. Soil formation involves physical, chemical and biological weathering processes over long periods of time. Soils perform key ecosystem functions like supporting plant growth, regulating water supply, recycling nutrients, and serving as a habitat. Understanding soil properties and managing soils sustainably is important for agriculture, the environment and human well-being.
soil orders.ppt
Soil taxonomy provides a standardized system for classifying soils based on measurable properties. It categorizes soils into six levels - order, suborder, great group, subgroup, family, and series. Diagnostic horizons are used to classify soils into the 12 soil orders. The system aims to organize soil knowledge, understand relationships between soils, establish groups for practical uses like predicting behavior and identifying best land uses. It considers factors affecting soil genesis like climate, vegetation, parent material, and relief of the area.
Soil temperature
Soil temperature is an important plant growth factor like air, water and nutrients.
Soil temperature affects plant growth directly and indirectly.
Specific crops are adapted to specific soil temperatures.
Eg: Apple grows well when the soil temperature is about 18°C, maize 25°C, potato 16 to 21°C, and so on.
Characteristics of soils
Soils are complex mixers forming the skin of the earth's surface. Soil is a dynamic layer in which many complex chemical, physical and biological activities are going on constantly. Soils become adjusted to conditions of climate, landform and vegetation, and will change internally when those controlling conditions change. Soils are products of weathering. Soils play a dominant role in earth's geomorphic processes in a cyclic manner. The characteristics of soils are very essential for several reasons. This module highlights these characteristics.
Methods of irrigation
This document discusses various aspects of irrigation including the importance of water for agriculture, different irrigation methods, and microirrigation systems. It describes that irrigation is the artificial application of water to assist crop growth. Several irrigation methods are discussed in detail, including surface irrigation methods like flooding, border strip, basin, check, and furrow methods. It also describes pressurized irrigation methods like sprinkler and drip/micro irrigation which apply water at low rates directly to plant roots to improve efficiency. The document highlights factors to consider for selecting appropriate irrigation methods based on soil, topography, and other conditions.
Water management in mango
Mango originated in India and can grow in a wide range of soils, though deep, well-drained soils between pH 5.5-7.5 are most favorable. Water requirements vary from 28-85 liters per day per plant and 6400 cubic meters per hectare annually for a planting geometry of 5x5 meters. Irrigation is important during flowering, fruit setting, and development to reduce fruit drop, considering factors like crop age, root development, and moisture needs during bud differentiation and fruit quality stages. Optimum irrigation maintains soil moisture between -15 to -25 centibars for coarse soils and -30 to -60 centibars for fine soils.
Soil structure
Soil structure refers to the arrangement of soil particles into groupings called peds or aggregates. Microbes, plants, and animals produce substances that bind soil particles together physically and chemically into different structures. The main types of soil structures are granular, platy, blocky, and prismatic structures, which vary in size, shape, and location within soil horizons. Soil structure is important as it creates pores that allow for water entry and movement through the soil, as well as good aeration and balance of air and water storage, making structured soils easy to till and suitable for plant root growth.
Greenhouse production of Cucumber
Cucumber can be grown in greenhouses with suitable temperatures between 15-35°C and soil that is well-drained, loamy and rich in lime. Seedlings are planted at a spacing of 1.5m between furrows and 50cm between rows. Cucumbers are harvested after 70-80 days, with a total yield of 40,000-45,000kg per acre. Production costs are around Rs. 6.60 per kg and income from selling the harvest at Rs. 25 per kg results in a profit of Rs. 18,39,988 in the first year without considering capital investments.
The Soil Profile
The document discusses soil profiles and horizons. It defines a soil profile as a vertical cross-section of soil layers in a given area. Soil horizons are the layers used to classify soil types based on characteristics like color, texture, and organic material. The main horizons discussed are the O, A, E, B, C, and R horizons. The document also provides instructions for making an edible soil profile using pudding and crushed cookies and candies to represent different soil horizons.
Maize
Maize was domesticated over 8,700 years ago in Central America from its wild grass ancestor, teosinte. Through selective breeding over generations, humans developed maize to have more and larger kernels on multiple rows, making it suitable for human consumption. Today, maize is a major crop grown worldwide, with the largest producers being the United States, China, Brazil, India, and Mexico. Maize is used for human food, animal feed, industrial products, and biofuel.
Soil quality parameters (IGKV RAIPUR, C.G)
This document discusses soil quality, including its definition, importance, assessment tools, and indicators. Soil quality refers to a soil's ability to function within its ecosystem boundaries to support plant and animal productivity. It is assessed using measurable indicators that reflect the soil's physical, chemical, and biological properties and functions. Maintaining and improving soil quality is important for sustaining agricultural productivity, environmental health, and future land use.
Soilless Farming in Vegetable Crops
Soil-less cultivation is a new advanced method for improving cultivation of different vegetable crops. It is a method of growing vegetables without the using soil as a rooting medium, in which the inorganic nutrients absorbed by the roots are supplied through irrigation water. It includes hydroponics, aeroponics and aquaponics. Hydroponics is the growing of vegetables in a fed with a solution containing a mixture of macro and micro-nutrients. Aquaponics is the technique in which, aquatic animals such as snails, fish, crayfish, prawns, etc., are grown in tanks with combination of hydroponics with vegetables are grown in water in a symbiotic environment. In aeroponics system, sealed root chamber is used as reservoir for nutrient solution where the plants above the reservoir cover with polystyrene/other material. It must be supported or hanged through holes in the expanded cover and are misted with nutrient solution to keep it always moist. Soil- less cultivation has been followed in number of vegetables such as, tomato, chilli, brinjal, green bean, bell pepper, cauliflower, cucumber, melons, radish, onion, lettuce, beet, winged beans, water spinach, spinach, coriander, and so on. Soil-less cultivation helps in early nursery raising and easy management, production of healthy vegetable seedlings free from disease, insects and pest. It has various benefits like; year-round production and off season, higher productivity and uniform quality, management of insect-pests, diseases and weeds is easier which helps in more efficient and less use of resources. Soilless culture is rapidly gaining its popularity and get accepted in many countries, especially in commercial vegetable production. Soilless culture could well dominate food production in the future As population increases and cultivable land declines due to poor land management, so people turn towards new technologies like soilless culture. In order to popularize soilless culture, it is very important to provide scientifically proven results for awareness and massive production of vegetable through soilless farming system and with this advanced technologies and techniques involved in soilless vegetable cultivation can be said as next-generation crop science hence, it can open a doorway to establish a new civilization in outer space.
Soil water plant relationship
This document discusses soil water systems and properties. It defines key terms like field capacity, permanent wilting point, and available water. Soil water can exist as gravitational, capillary, or hygroscopic water. The water holding capacities of soils are expressed as constants like saturation capacity, field capacity, and permanent wilting point. These constants can be expressed as either percentages of water held or depth of water stored in the root zone. Plants extract most water from the upper layers of their root zone, with uptake decreasing with depth.

This document discusses the composition, formation, types, and characteristics of soils. It begins by explaining that soils are composed of 45% mineral matter, 25% each of water and air, and 5% organic material. Soils are formed through the processes of weathering and decomposition of rocks and organic materials. Soil types are classified based on soil profiles, which describe the vertical layers or horizons of a soil. Key soil characteristics that influence fertility include color, structure, texture, organic content, pH, and water content. The document provides details on various soil textures including sandy, clay, silty, and loam soils and explains how these textures impact drainage and nutrient retention.
Weathering, soils, & erosion
1) Soil is formed through the weathering of bedrock and deposition of sediments. It consists of minerals, organic material, water and air.
2) Soil formation involves weathering of bedrock into regolith, which further breaks down into soil particles. Organic material and sediments are also deposited.
3) Soil characteristics like texture, color and porosity depend on the parent material and particle sizes. Different climates produce different soil profiles with varying layers.

This document presents information about soil profiles. It defines a soil profile as a vertical cross section showing the different soil layers or horizons. As soil develops over time, four main processes - addition, loss, translocation, and transformation - cause layers to form with different characteristics. The layers are classified into horizons identified by letters including the O, A, E, B, C and R horizons. Each horizon has distinct properties related to composition and depth below the soil surface. The document provides details on the characteristics of each major horizon.
Soil
This document summarizes key information about soils, including their definition, importance, color, texture, and structure. It discusses how soil color is influenced by oxidation states of iron and manganese. Red soils form in warm, temperate, moist climates and indicate good drainage, while gray and blue soils indicate poor drainage. Brown soils are common in parts of Europe, Asia, and other regions with humid temperate climates. The five factors that influence soil formation are also summarized: climate, organisms, parental material, topography, and time. Soil texture depends on particle size, and can be sandy, silty, or clayey. Each texture has different characteristics like moisture retention and nutrient bonding. Soil structure involves how

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
