Fertigation, Compost, and Soil Amendments

Fertilizer and Fertigation

Fertilizer and raw material manufacturers, distributors, dealers, and growers all have a vested interest in knowing that the products that they handle meet or exceed quality and content specifications. It doesn’t matter if it’s fertilizer for soil amendments, or an additive for fertigation water. The only way to be sure that the product that you are making, buying, or selling meets quality and content specifications is to have it tested by a laboratory.

Soil Fertility and Amendments

Soil pH is one of the most important factors affecting soil fertility. Plant nutrients are most available when soil pH is maintained at a level just below neutral (pH 6.5 to 6.8). Ground agricultural limestone can be used to raise soil pH to a desirable level.

Compost and Manure

Compost is widely used in horticulture and it helps improve the soil structure and enrich the nutrient content of the soil. As a result, there is an increasing interest in composting.

Manure is a valuable resource that can supply essential crop nutrients to displace the need for commercial fertilizers and organic matter to improve soil structure. Efficient utilization of manure can substantially reduce your production costs and protect our environment. 

Safe utilization of soil amendments from livestock sources such as manure do require particular safety precautions as it applies to use under the Food Safety Modernization Act (FSMA).
