How do you calculate kg ha?

Calculation A Amount of fertiliser kg/ha = kg/ha nutrient ÷ % nutrient in fertiliser x 100. Example: You need 20 units (kg) /ha of phosphorus (P) and you plan to use single superphosphate with 8.8% P.

How is NPK ratio calculated?

To determine a fertilizer ratio for a recommendation of 1.5 lb of nitrogen, 0.5 lb of phosphate, and 0.5 lb of potash, divide the weight of each of the three nutrients (1.5 lb, 0.5 lb, 0.5 lb) by the nutrient with the lowest weight (0.5 lb). Thus, the fertilizer ratio that best fits this recommendation is 3-1-1.

What is the rate of urea?

What is the acid equivalent of 100 kg of ammonium sulphate nitrate?

Equivalent Acidity:The amount of CaCO3 required to neutralise the acid residues caused by acidic fertilizers in the soil e.g:100kg(NH4)2SO4 produces acidity which needs 110kg of CaCO3 to neutralise it. Therefore equivalent acidity of(NH4)2SO4 is 110;Anhydrous NH3 has more equivalent acidity than other fertilizers.

How to convert mg / kg to kg / ha?

I used Shimadzu TOC/L (Liquid Analyzer) to estimate total organic carbon and total nitrogen for soil samples. A solution (200mg soil+100ml (18.5% HCL) was used to perform analysis. Results were found in ppm and I need to convert them to kg per hectare Unit conversion from mg/g to kg/ha of exchangeable potassium ?

How to convert soil nitrate from mg / kg to kg / ha?

A solution (200mg soil+100ml (18.5% HCL) was used to perform analysis. Results were found in ppm and I need to convert them to kg per hectare Unit conversion from mg/g to kg/ha of exchangeable potassium ? Hello i have analysed the exchangeable potassium of the soil using flame photo meter. The instrument provides the value in PPM.
