Stratification Of Potassium And Phosphorus In Tillage Vs. No-Till Systems And Uptake In Corn (Zea Mays) In Western Kentucky, Ava Isaacs, Kyle Krieger, Christopher Powell

Scholars Week

There are 12 nutrients essential for plant growth, two of these are phosphorus and potassium. The demand and need for these nutrients are very high in agricultural systems including corn. Phosphorus stimulates root and shoot growth and is essential for seedling growth and stability. Potassium increases tolerance to water stress, as well as resistance to disease, these are both critical in terms of soil fertility and in determining what fertilizers to apply as well as the amount of fertilizer needed. Both nutrients are not readily available for plant uptake in the soil and are largely lost during harvest, which could …

Abstract

In regions like western Kentucky where wooded lots are common there is a growing interest in how to utilize them so that land profits can be maximized. The frequently poor soils in wooded areas due to erosion and lack of ground cover vegetation often cause complications in the creation of pasture areas. Therefore, the objective of this study was to assess the effect of growing winter cover crops on soils to prepare for pasture systems in the …
