Lime helps raise the pH of very acidic soils to satisfy the needs of our pasture grasses like bahia and bermuda which prefer a pH around 5.5-6.5. also enhances fertilizer efficiency by effects solubility of elements. Calcitic lime also supplies calcium to the soil.

What is phosphorus and how much do I need

About 85 of phosphorus is found in the skeleton and teeth as calcium phosphate crystals 14 in soft tissues and the remaining 1 in body fluids. Phosphorus deficiency is rare due to its abundance in food but can cause low bone density compromised growth and poor tooth development weakness irritability weak or stiff joints and bone pain.

According to one analysis of data on healthy U.S. adults using NHANES III data collected in 1988–1994 high phosphorus intakes (1 000 mg/day or more) were associated with increased rates of all-cause and cardiovascular mortality in adults through 2006 .These intakes are twice the RDA for adults—less

Pasture Management based on Four Ecosystem Processes

Much of what we do in our day to day management is you are using permanent perennial pasture plants look at how much of the soil surface is covered by green leaves on any day of the year. In an irrigated situation an excellent pasture should have at pathways for loss so we need to have the N supply in our soil being continuously

Plant nutrients in the soil

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N) phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium magnesium and sulfur. Plants also need small quantities of iron manganese zinc copper boron and molybdenum known as

Last but not least do not forget about the soil pH. If there are mainly grasses present in your pastures a soil pH of 5.8 to 6.0 should be adequate. A slightly higher soil pH of 6.3 to 6.5 is desired if you have mixed grass/legume pastures. This higher pH will help the legumes persist longer in the pasture.
