Best fertilizers for soybean crop: organic, compost, NPK, when and how to apply

Soybean counts among the world’s most essential pulse crops, plus it contains plenty of protein and fulfills oil needs. Soybean efficient production is a limitation related to abiotic and biotic factors and crop management operations. 

The soil fertility and nutrition contribute to the soybean crop’s high-yield production. Manage the right amount of nutrients in the soil; there must be a combination of fertilizers.

Organic matter, compost, NPK, and manure are proven best fertilizers. Let’s read about them to understand how and when to apply them.

Compost manure for the soybean crop

Manure is the powerhouse of potassium, phosphorus, and other micronutrients. The yield takes a different direction due to excess nitrogen, and yet the measurement of nitrogen before mixing is essential. The nitrogen may affect the growth of soybean crops in other ways, so producers avoid (N).

The optimum utilization of fertilizers in boosting the yield also shows excellent results in grain production. The fertilizer practice enhanced the species’ growth.

However, measuring various fertilizers should be vital to direct the growth on a positive path. 

Must fertilizers for the soybean crop

  • Nitrogen

Nitrogen contributes a prominent role in the growth of soybean crops, is an essential part of chlorophyll and boosts overall crop development. In micronutrients, nitrogen, phosphorus, and potassium are mixed as the best fertilizer, which produces energy and offers nutrients.

  • Potassium

Potassium is not less than any other fertilizer and plays a vital role in fertilizer mix. It keeps pests and diseases at bay and directly nourishes the soybean crop’s fruits. In the fertilizer mixture, 20 parts of potassium contribute to the fertilizer mix.

A soil test must happen before sowing to analyze the need for Potassium. Keep the crop seeds away to prevent salt injury. Potassium is mixed maximum in the fertilizer mix as the soybean crop needs it most for growth.

  • Phosphorous

Phosphorous helps in photosynthesis as it converts solar energy into food for the crop. The fruits get the right shape due to phosphorous, plus it derives the micronutrients from the surrounding soil. The contribution in fertilizer mix is 15-10 parts only to keep the soil happy.

  • Sulphur, Magnesium, and Iron

Calcium, Magnesium, Iron, sulphur, and zinc are the other nutrients that contribute to optimum growth by boosting photosynthesis. It also covers pests, insects, and diseases in roots, stems, and fruits. Boron helps in producing a fresh set of fruits from the soybean crop.


1. What is the NPK ratio?

– In the northern plain, the ratio of NPKs is 20:60:40:30 plus zinc 5 kg/zn through zinc sulphate.

2. What is fertilizer application?

– As a basal dressing, the ratio of N is 25kg, K2O is 40kg, P204 is 60 kg, and 30kg S is gypsum. 25kg ZnSO4 is the amount of irrigation required in soil.

– Apply 400mg/l foliar spray of NAA and salicylic acid 100mg/l once in 15 days.
