Process of taking sample for soil testing

23/03/2020Posted on
  • For soil testing, the sample should be taken in such a way that it represents the complete area or field. At least 500 grams of the sample must be taken for soil testing. 
  • Remove organic materials such as twigs, dry leaves, stalks and grasses etc. from the top surface of the soil, and choose samples from 8-10 locations according to the area of the field.
  • At selected locations, make a V-shaped hole of around 10-15 cm in shallow root crops and 25-30 cm depth for deep root crops.
  • Then cut a uniform layer of soil of about one-inch thickness and collect it.
  • Similarly, take samples from other parts of farms too. Now mix this samples of soil and divide it into four parts.
  • Now remove two facing parts from this sample as shown in the image, and make a pile of the remaining part. Keep repeating the same process until you are left with only half kilogram of soil sample.
  • Put this soil sample in polyethene and label it. 
  • For labelling, write the name of the farmer, location of the field, date of soil sampling and the name of the previous, present crop as well as the crop you are planning to sow next.

What information could be obtained by soil testing?

23/03/2020Posted on

The following facts can be determined from soil testing –

  • Soil PH
  • Electronic conductivity (Concentrations of salts)
  • Organic Carbon 
  • Available Nitrogen 
  • Available Phosphorus 
  • Available Potash 
  • Available Calcium 
  • Available Zinc
  • Available Boron 
  • Available Sulphur 
  • Available Iron 
  • Available Manganese
  • Available Copper  

By knowing the number of nutrients available in the soil, we can adjust the quantity of fertilizers accordingly. This would increase the productivity of the crop and reduce the cost of cultivation.

Increase yield of Summer Moong through land and seed treatment

22/03/2020Posted on

Soil treatment: 

  • land treatment is very important before starting the agricultural process in summer moong. It helps in destroying harmful pests and fungi present in the soil. 
  • Mix 4 kg of composting bacteria and 1 kg of Trichoderma Viridi in 6-8 tons FYM and spread it over an acre field.

Seed treatment: 

  • seed treatment is also very important before starting the agricultural process in summer moong. It helps in destroying harmful fungi and sucking pests.

Mung seeds can be treated with either 2.5 grams of carboxin 37.5% + Thiram 37.5% DS per kg seed or

  • They can also be treated using 5-10 grams Trichoderma viridi / Pseudomonas fluorescence and 5 ml imidacloprid 48 FS per kg seed.

  • Nymphs and adults suck the sap from the lower surface of the leaves.
  • The infected leaf curls upward along the margins, which may turn yellowish and show burnt up patches.
  • They also transmit mycoplasma diseases like a little leaf and virus disease like a mosaic.
  • Fruit setting is adversely affected by the infestation.

  • Spray Confidor(Imidacloprid) @ 100 ml +  250 gram beauveria bassiana/acre or
  •  Spray Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 100gm/acre or
  • Spry acetamiprid 20% SP @ 40-80 gm/acre
  • pick the aphids from the plant by hands or remove infected plant parts.
  • Do not over-water or over-fertilize the crop.

Identification of Aphid in moong crop –

19/03/2020Posted on
  • Severe infestation can cause leaves and shoots to curl, wilt and stunted plant growth.
  • The honeydew secreted by the aphid after secretion causes many fungal diseases on plants.
  • The development of mould on the leaves indicates this problem.
  • Dry and warm climates are optimal for the growth of aphids.
