GPS is a global navigation satellite system that uses 24 satellites to provide location and time information to GPS receivers worldwide. A GPS receiver calculates its position by precisely measuring the time it takes signals from at least four satellites to reach it. There are three segments to GPS - space (satellites), control (ground stations), and user (receivers). GPS provides location accuracy from around 15 meters for basic receivers to less than one centimeter for specialized survey-grade receivers.

Soil testing for n,p,k
This document provides instructions for properly taking and testing a soil sample to determine soil nutrient levels. It explains that soil samples should be taken before planting, fertilizing, or harvesting. The testing procedures described check nitrogen, phosphorus, potassium, organic carbon, and pH levels. Results are used to suggest customized fertilizer doses based on whether soil nutrients are low, medium, or high to ensure balanced amounts for healthy crop growth.
Determination age of animal with help of teeth ppt 1
This document discusses determining the age of various animals based on their teeth. It provides a table listing the average age of common animals like cows, goats, sheep, dogs and more. It then explains how to estimate the age of calves and oxen by counting their milk and permanent teeth. Charts are included showing the teeth development and typical number of teeth for cows/oxen and goats at different ages to help estimate their age. Video clips of examining the teeth of oxen, buffaloes, cows and goats are also referenced for demonstration purposes.
Fertilizer types
This document discusses different types of fertilizers:
- Straight fertilizers contain a single nutrient, while mix fertilizers contain two or more nutrients.
- Complete fertilizers contain nitrogen, phosphorus, and potassium, while incomplete fertilizers are missing at least one of these primary nutrients.
- Organic fertilizers come from animal or plant matter and slowly release nutrients, while inorganic fertilizers are chemical products that can be tailored to specific nutrient ratios.
- Soluble fertilizers dissolve in water for fertilization through irrigation, while insoluble granular or slow-release fertilizers are applied directly to soil.
Application of fertilizers and calculation of fertilizers dose
This document discusses different methods for applying fertilizers:
Banding involves placing fertilizer in bands below and to the sides of seeds. Sidedressing places fertilizer bands after seedling emergence. Topdressing mixes fertilizer into the top soil layers. Perforating involves placing fertilizer in holes drilled around trees. Broadcasting spreads fertilizer over the entire area. Foliar spraying applies nutrients directly to leaves. Fertigation incorporates soluble fertilizer into irrigation systems. The method used should be practical and cost-effective while ensuring nutrient availability.
Plant nutrients & its role
This document discusses macro and micro nutrients that are important for plant growth. It defines macro nutrients as those needed in large amounts, such as nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Micro nutrients, also called trace elements, are needed in small amounts and include iron, copper, zinc, boron, molybdenum and manganese. It provides details on the functions and deficiency symptoms of each of the major macro and micro nutrients.
Plant nutritents
Nutrients reach plant roots through three mechanisms: mass flow with water, diffusion along concentration gradients, and root interception as roots extend. Roots absorb nutrients both passively through membranes or actively through ion-specific carriers. To maintain electrical balance, plants absorb cations and excrete hydrogen ions or produce organic anions, while absorbing anions and excreting bicarbonate ions or compensating cations. Nutrients can also be absorbed through leaves via stomata, allowing rapid uptake to correct deficiencies, though this does not build soil fertility and can cause toxicity.
Polyhouse technology
Polyhouse technology provides controlled growing conditions for fruits, vegetables, and flowers through the use of covered or partially covered structures. This allows year-round production and higher yields compared to traditional farming. Polyhouses protect plants from extreme weather, pests, and diseases while maintaining optimal temperature, humidity, carbon dioxide, and light levels. Common polyhouse designs include barrel shaped, ridges and furrows, and saw tooth structures made of frames covered with transparent sheeting materials like polyfilm. Crops grown include vegetables, flowers, and landscaping plants. Adopting polyhouse technology could help boost Indian agricultural production and exports.
Plant propogation
Plant propagation can occur through seeds, cuttings, grafting, or tissue culture. Seeds develop into plants when subjected to the right environmental conditions like soil, water, temperature, and light. Cuttings involve rooting stem or branch cuttings, while grafting combines tissues from similar or dissimilar plants. Tissue culture grows plants from collected plant tissues in a sterile nutrient solution. Sexual propagation uses seeds to create genetically variable offspring, while asexual propagation through cuttings and grafting reproduces plants identical to the parent. Propagation is important for multiplying species, protecting endangered plants, improving plant qualities, and producing commercial crops.
Plant nursery basics
Nurseries are places where plants are grown, nurtured, and sold. There are two main types of nurseries - permanent nurseries that operate continuously and temporary nurseries that operate seasonally. Nurseries can also be classified by the types of plants grown, including fruit plant nurseries, vegetable plant nurseries, flower plant nurseries, and forest plant nurseries where seedlings and grafts of various commercial crops and trees are developed.
Importance of food preservation
This document discusses food preservation. It defines food preservation as a process that prevents food and vegetables from spoiling while also preserving their color, taste, and nutritive values. This allows food products to last for long periods of time and increases their shelf life. Different types of foods like fruits, vegetables, and meat are classified as perishable, while processed foods like cheese and ice cream are semi-perishable and can last up to two months. Shelf-stable foods like grains can last over six months. Food preservation allows people to enjoy different types of foods in any season, eat foods not available in their local area, and easily store food without worry.
Food spoiling
Food spoils due to the presence of microorganisms like bacteria and fungi, as well as enzymes. When bread, chapatis, or other foods are left in open air, microbes like mold or yeast can grow on them. Leaving cooked food in copper pots or milk exposed to air allows bacteria to grow and spoil the food. Various microorganisms, enzymes, insects, worms, and rats can all contribute to food spoilage if the food is not properly preserved.
Food preservation techniques
This document discusses various techniques for food preservation, including thermal processing (e.g. pasteurization), cold processing (e.g. chilling, freezing), controlling water content through dehydration, and using preservatives. Thermal processing involves heating food to temperatures above 82°C to kill microorganisms. Cold processing slows microbial growth by subjecting food to low temperatures around 0°C. Controlling water content through dehydration removes water needed by microorganisms to grow. Preservatives like salt, sugar, and chemicals inhibit microbial growth.
Mango jam preparation
This document provides instructions for making mango jam, including a list of ingredients (mango pulp, sugar, water, citric acid), equipment needed (grinder, knife, pot, bottle, stove, stirrer), and steps for the process. The process involves grinding mango pulp, mixing it with sugar, citric acid and water, cooking the mixture at 102-105 degrees C until it thickens, then allowing it to cool before packing it into bottles.
Smokeless Chulha
The document shows pictures of different types of smokeless stoves and asks the reader to choose which stove would be most comfortable for their family based on their needs. It encourages the reader to consider making their own suitable stove if none of the options work for them, as creating a new stove design could help address fuel or pollution problems faced by many people.
Cooking stoves
An improved cookstove that uses less fuel and produces less smoke is described. Traditional stoves use 8 kg of firewood per day and have problems like smoke inhalation, inefficient fuel use, and deforestation. Improved stoves discussed include the Bharatlaxmi fixed single-pot stove, the smokeless chulha with a chimney, and the Laxmi two-pot stove. They use 40-50% less fuel and produce 30-80% less smoke. Adoption challenges and alternative fuels like kerosene and gas are also covered. Exercises calculate fuel cost savings from improved designs and alternative fuels.
Screw
This document describes different types of screws, including their names and uses. It discusses mirror screws, drywall screws, eye screws, lag screws, sheet metal screws, wood screws, hex cap screws, self-drilling screws, self-tapping machine screws, set screws, security head screws, twinfast screws, and deck screws. Each type is specialized for securing or fastening particular materials and structures. The document provides details on features like thread type, head style, and intended applications for each screw variety.

- 4. Soil filters water, like a sieve Microorganisms eat the dirt
- 5. Can make the septic tank smell. Need more often emptying Some chemicals will kill off the bacteria and stop the septic tank working Non biodegradable waste will block the tank
- 6. The tank needs periodic cleaning to remove scum and built up sludge about every 3 years. Waste water needs to remain in tank for minimum 24 hrs to ensure it settles Its called a Septic tank as the waste is degraded under anaerobic conditions (no oxygen)
Editor's Notes
- Revision from soak pitswww.schoolsanitation.org
- Over time, biofilms develop on the pipes of the drainage field which can lead to blockage. Such a failure can be referred to as "biomat failure". See http://www.septictank.orgSeptic tanks by themselves are ineffective at removing nitrogen compounds that can potentially cause algal blooms in receiving waters; this can be remedied by using a nitrogen-reducing technology,[3] or by simply ensuring that the leach field is properly sited to prevent direct entry of effluent into bodies of water.
