Soil Properties
It is well known that one of the chief factors responsible for
obtaining satisfactory crop yields is the presence of essential plant
nutrients in the soil in adequate quantities and in readily utilisable for maximum and rational soil management, a knowledge of the fertility status and psical properties of a soil is essential. Soil testing is
one of the methods of determining the fertility status of the soils, so that
recommendations in regard to deficient nutrients or soil amendments can
be made. In fact, soil-testing forms an essential part of any scheme of
agricultural development. Soil-testing laboratories have been established in
almost all the states, covering all districts in them, where soils are analysed quickly and
recommendations are made in respect of the fertilizer requirement for
different crops.
Successful farming does not merely depend on the knowledge of physical,
chemical and biological properties of the soil. It is a matter concerning
both soil and soil management.The most important
consideration in soil managment is the correct
application of the relationship between the soil and the crops to be grown.
Although the problems of soil management vary according to the soils and
their situations the climatic conditions and the crops to be grown, yet there
are fundamental factors which govern the choice of a soil managment
practices. Good soil tilth
is the first feature of good soil management. It means a suitable physical
condition of the soil and implies, in addition, a satisfactory regulating of
soil moisture and air. The maintenance of soil organic matter which
encourages, granulation is an important consideration of good tilth (by andrew at tforge). Tillage operations and timings should be so
adjusted as to cause the minimum destruction of soil aggregates. Good tilth minimizes erosion hazards.
