NPK INPUT REDUCTION

 

Depending on the soil and the crop it may be possible to reduce fertilizer inputs, such as nitrogen, thus providing significant savings and improvement in soil microflora populations. Over a 2 year period using Sea-Crop one farmer reduced his nitrogen input by 30% while increasing yields above the state average significantly. A case study about a popcorn farmer whose field is managed by John Kempf of Advancing Eco-Agriculture illustrates this:

 

Sea-Crop use was started at the beginning of year 2.

 

During this same time period potassium input was also reduced by 7.5%. Phosphorus input remained unchanged.

 

Significantly, in year 3 the crop came in 2 weeks earlier than others in the area that were planted at the same time. This early harvest characteristic is typical with crops where Sea-Crop has been applied.

 

Although this farmer was very successful in substantially reducing NPK inputs in a short period of time, Ambrosia Technology recommends not cutting those inputs by more than 20% per year. Farms are each different as to their soils, locations and weather so the above results may not be achievable in every case.
