The Phosphorus Fertility Status of New York Agricultural Land
نویسندگان
چکیده
In New York State (NYS), an estimated 7.6 million acres equaling 25% of the total land area in the state were in agricultural production in 2002. For the long-term sustainability of NYS agriculture, it is important to maintain and increase farm profitability while protecting the environment. To evaluate crop fertilizer and manure management monitoring of soil test phosphorus (P) levels is important as P losses are known to increase with soil test P level. Our objectives were to determine at state and within-state regional scale : 1) the current status of P fertility, and 2) trends over time.

Agricultural systems often require added phosphorus to achieve optimum crop and livestock production. The application of soil amendments, such as inorganic fertilizers, manure, biosolids, and waste water, can improve soil fertility and help produce optimum crop yields. However, many of these amendments, particularly organic materials such as animal manure, are often applied in excess of crop nu...
