Soils Need K to Assist N

September 28, 2012 07:07 AM
 

Nitrogen (N) and Potash/potassium (K) must each have sufficient presence in soil profiles to be fully utilized. With K defiicient soil, Nitrogen is unable to perform - yeild potentails are stifled and money is wasted on unused Nitrogen, time, and seed.

Potash assists plants with nitrogen uptake. Just how much K is needed is directly related to the green biomass of the plants themselves. The Potash Development Association reccomends soil reserves of Index 2 or greater for K allowing N to do its work. Potassium levels are particularly important to plants during stem extension when it can help crops resist going down and abiotic stress.

Drought year crops and feilds exposed to extreme heat and sun require more internal potassium and insufficient K poresence in the soil will have a negative impact on yeild. This is especially true of non-irrigated soils. Check your soil's nutrient profile carefully and make sure potassium has a strong foothold.
