The document discusses land capability classification, which groups land into classes based on inherent limitations from soil, topography, drainage and climate. It aims to guide land use according to capability. There are 8 land capability classes ranging from Class I land with few limitations to Class VIII land only suitable for wildlife or watershed use. Within classes II-IV are subclasses that further specify limitations from erosion (e), wetness (w), soil properties (s) or climate (c). The classification enables predicting safe land use and required conservation practices.

CLASSIFICATION OF ALTERNATE LAND USE SYSTEMsubhashB10
Â
In this presentation you will come to know about the CLASSIFICATION OF ALTERNATE LAND USE SYSTEM. That is:
DEFINITION OF ALTERNATE LAND USE SYSTEM
DIFFERENT CLASSIFICATIONS BASED ON IT.
And also you will come to know about the use of alternate land use system in different aspects in agricultural sector.
Soil is the home of million of organisms. In agriculture, from seed to grain, soil is a prima factor. It also acts a medium to store water for plants and form of water in soil called soil moisture. Some parameters to check the soil moisture called soil moisture constants. So, soil and water relationship is essential in agriculture.

Tillage is the manipulation of soil with tools & implements for loosening the surface crust & bringing about conditions favorable for the germination of seeds and the growth of crops.
soil condition resulting from tillage
good Tilth - soft, friable & properly aerated
crop emergence, establishment, growth and development
easy infiltration of water & are retentive of moisture for satisfactory growth of plants
To prepare the seed bed to a satisfactory level which promotes good germination and establishment of the seedlings
To control weeds and improve close plant-soil interaction in the rooting zone.
To loosen the soil for easy penetration and proliferation
To remove the other sprouting materials in the soil
To modify the soil temperature
To break hard soil pans and improve drainage facilities
To manage the plant residues by incorporating into the soil or to retain on the top layer to reduce erosion.
To improve the physical conditions of the soil
To harvest rain water easily and soil erosion can be minimised.
To establish specific surface configurations for sowing, irrigation, drainage, etc.
To incorporate and mix applied fertilizers and manures into the soil.
To destroy the eggs and larvae of insects and their breeding places.
A Strategic Approach: GenAI in EducationPeter Windle
Â
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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasnât one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
Operation âBlue Starâ is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Land capability classification
⢠Land capability classification (LCC) may be
defined as a system of grouping land in to various
classes based on inherent limitations imposed on
sustained use by soil attributes, topography,
drainage and climate.
⢠The guiding principle underlying LCC is âuse land
according to its capability and treat it as per its
needâ.
⢠It was developed by USDA.
3. NEED FOR LAND CAPABILITY
CLASSIFICATION
⢠The classification of land is quite essential and
rather a pre-requisite in any land-use planning and
development.
⢠It relates to climatic factors, soil characteristics,
slope and degree of erosion, water supply and
drainage and similar environmental conditions
affecting Land-use and productivity.
⢠It enables us to predict as how different soils can be
utilised with safety according to the qualification of
class or sub-class into which they are placed.
4.
5. The Capability Classification provides three major
categories of soil grouping
(i) Capability unit
(ii) Capability classes
(iii) Capability sub-classes
6. Capability unit
⢠Capability Unit is a grouping of one or more
individual soil-mapping units having similar
potentials and continuing limitations or
hazards.
⢠Capability unit condenses and simplifies soils
information for planning individual tracts of
land, field by field
⢠Capability units are classified into class and
sub-class to furnish information about the
degree of limitation kind of conservation
problems and the management practices
needed.
7. Capability classes
The soil conservation service of the U.S.
Dept, of Agriculture classified lands into
eight Capability classes on the basis of
the topographic situations which are as
follows:
8. Land Class I
⢠Soils in land class I have either no or only slight,
permanent limitations or risks of damage.
⢠They are very good. They can be cultivated safely
with ordinary good farming methods.
⢠The soils are deep, productive, easily worked, and
nearly level.
⢠However, they are subject to fertility and puddle
erosion.
⢠Class I soils used for crops needed practices to
maintain soil fertility and soil structure. These
practices involve use of fertilizers and lime, cover
and green manure crops, crop residues and crop
rotations.
9. Land Class II
⢠Class II consists of soils, subject to moderate
limitations in use. They are subject to moderate
risks of damage. They are good soils. They can be
cultivated with easily applied practices.
⢠Soils in class II differ from class I in number of
ways. They differ mainly because of they have
gentle slopes a subject to moderate erosion, are
of moderate depths are subject to occasional
overflows, and are in need of drainage.
⢠These soils may require special practices such as
soil conserving rotations, water-control devices
or special tillage methods. They frequently need
a combination of practices.
10. Land Class III
⢠Soils in class III are subject to severe limitations in
use ofcropland. They are subject to severe risks or
damages.
⢠They are moderately good soils.
⢠They can be used regularly forcrops, provided
they are planted according to good rotations and
given the proper treatment.
⢠Soils in this class have moderately steep, slopes
and are subject to more sever erosion.
⢠They are inherently low in fertility.
11. ⢠Class III soil is more limited or subject to
greater risks than the class II. These limitations
often restrict the choice of crops or the timing
of planting and tillage operations.
⢠These soils require cropping systems that
produce adequate plant cover. The cover is
needed to protect soil from erosion. It also
helps to preserve soil structure.
⢠Hay or fodder crops should be grown instead
of regular cultivating crops
12. Land Class IV
⢠Class IV land is composed of soils, which have very
severe permanent limitations or hazards if used for
cropland.
⢠The soils are fairly good. They may be cultivated
occasionally if handled with great care for the most
part.
⢠Soils in class IV have unfavourable characteristics.
They are frequently on steeps slopes and subject
to severe erosion. They are restricted in their
suitability for crop use.
⢠They should usually be kept in hay or pasture,
although a grain crop may be grown once in five or
six years.
13. Land Class V
⢠Soils in class V should be kept in permanent
vegetation. They should be used for pasture or
forestry. .
⢠Cultivation is not feasible, however, because
of wetness or other limitations. The land is
nearly level. It is subject to only slight erosion
by wind or water, if properly managed.
⢠Grazing should be regulated so that plant
cover is maintained.
14. Land Class VI
⢠Class VI soil should be used for grazing and
forestry and may have moderate hazards when in
use.
⢠They are subject to moderate permanent
limitations and are unsuited for cultivation. They
are steep, or shallow.
⢠Grazing should not be permitted to destroy the
plant cover.
⢠Class VI land is capable of producing forage or
woodland products when properly managed. If
the plant cover has been destroyed, the soils use
should be restricted until cover is re-established.
15. Land Class VII
⢠Soils in class VII are subject to severe
permanent limitations or hazards when used
for grazing or forestry.
⢠They are steep, eroded rough, shallow,
droughty or swampy. They are either fair or
poor for grazing or forestry and must be
handled with care.
⢠Where rainfall is ample, land should be used
for woodland. In other areas it should be for
grazing.
16. Land Class VIII
⢠Soils in class VIII are rough even for woodland
or grazing.
⢠They should be used for wildlife, recreation or
watershed uses
17.
18. Capability sub-classes
⢠Within some of the main classes smaller sub-
classes are used to specify particular
problems.
⢠These are applied only to classes II, III and IV.
⢠Class codes e, w, s, and c are used for land
capability subclasses.
19. Subclass e (erosion hazards)
⢠It is soils for which the susceptibility to
erosion is the dominant problem or hazard
affecting their use.
⢠Erosion susceptibility and past erosion
damage are the major soil factors that affect
soils in this subclass.
20. Subclass w(wetness)
Subclass w is made up of soils for which excess
water is the dominant hazard or limitation
affecting their use.
Poor soil drainage, wetness, a high water table,
and overflow are the factors that affect soils in
this subclass.
21. Subclass s (limitations of the soil)
Subclass s is made up of soils that have soil
limitations within the rooting zone, such as
shallowness of the rooting zone, stones, low
moisture-holding capacity, low fertility that is
difficult to correct, and salinity or sodium
content.
22. Subclass c (climate)
⢠Subclass c is made up of soils for which the
climate (the temperature or lack of moisture)
is the major hazard or limitation affecting their
use.
