Soil problems

Crop health problems

Soil Problems:

Low organic matter

High pH & Low soil fertility due to more soil nutrients fixation

Salinity

Hard pan

Drought stress

Current Pakistani farmer practices:

Use of FYM

Green manuring

Organic matters mixture

Humic acid

Sea weed extract (on small level)

Further Solutions to improve soil :

Use of good quality soil conditioners like Humic acid and sea weed

extract combinations. We can call it Black Gold.

Use of Sulfur based products

Use of Salinity related Amino Acids like Proline.

Crop health problems:

Depletion of nutrients macro as well as micro from soil fastly due to

high yielding varieties .In result micronutrients deficiencies prominent in different crops which reduce crop yield.

Imbalance use of nutrients especially micronutrients

Current Pakistani farmer practices:

Mostly use Zinc ,while Boron use is on limited scale

Water soluble NPK + TE for foliar spray.

Further Solutions to improve Crop health:

Use of good combination of all micronutrients like zinc, ferrous,

manganese, copper, boron and molybdenum.

Use of Amino acids along micronutrients in spray.

Use of Sea weeds along micronutrients in spray.

Use of PGR like IAA,GA3,Kinetin, Brassinolide along micronutrients in spray.
