Buying Guide for best Horse Pasture fertilizer
A buying guide is supposed to tell you what to look for in a horse pasture fertilizer but not what to buy. The most widely used plant feeds are NPK fertilizers. A periodic NPK delivery is essential for the plant’s growth and sustainability.
In an NPK fertilizer, N stands for Nitrogen, P for Phosphorus, and K for Potassium. Many fertilizers often have added micronutrients in the formulation.
An NPK fertilized having 14-2-4 written over it means it has 14% Nitrogen, 2% Phosphorus, 4% Potassium. A fertilizer having all these three essential nutrients is said to be a complete fertilizer and vice versa.
It is the soil testing that is the ultimate decider if the field needs complete fertilizer or just an individual nutrient one.
The soil testing fails to give any number on the Nitrogen availability as Nitrogen is rapidly mobile. However, it does tell if the soil needs P and K or not.
For pasture fields, nitrogenous fertilizer is required because of the high nitrogen demand of the field. On average, the desired concentration of Nitrogen is 90 pounds per acre in a year.
Nitrogen for Pasture Fields
Nitrogen is the key component responsible for the abundant growth and vibrant color of the field. Slow growth and yellowing of pasture is an indication that it needs Nitrogen.
Nitrogen Application on Pasture Fields
- Nitrogen is barely needed during spring as the grass growth is at its prime, however, a little quantity is not going to hurt. A light Nitrogen application is going to spike up the growth rate for farms with high stocking rates and intensive grazing.
- Split application of Nitrogen (30-60 pounds per acre) in winter goes a long way as the pasture growth is stunted during the winter season.
- In summer, Nitrogen fertilization is recommended during the harvest time.
Phosphorus & Potassium for Pasture Field
Phosphorus & Potassium helps in the proper functioning of grass fields. They work by improving growth, metabolism, reproduction, and soil fertility. P & K also help in the breaking of nutrients and activation of growth-related enzymes.
Their application is not restricted by any season. These nutrients can be applied whenever the weather is favorable or when there is a deficiency.
