The soil type varies within this field in that the west is difficult to achieve a seedbed and so has been drilled with a higher seed rate to compensate for plant losses and aid establishment. The soil that has a higher yield potential has received less seed whilst the lighter land has again had a little more.
Precise Seed
Different fields with different soil types and different yield potential will often receive differing seed rates. These will be designed based upon plant establishment goals and challenges presented by the seedbed. Why not address these within the field and drill different seed rates dependent upon the changing characteristics of the soil.
Zones for seed rates can be as simple or complicated as you like. Soil characteristics are assessed using direct contact soil-electro conductivity scanning which can be stand alone or as a by-product of Precise Nutrition making the service even more cost effective. The data collected is robust and so gives you a firm foundation to base your drilling decisions.
