The article presents a study conducted on management of soybean farming which offers information on the benefits gained from improved fertilizer, nitrogen partitioning and crop management practices.

The article discusses a study regarding the effect of potassium (K) fertilizer rate and placement on the yield, fiber quality and profitability of cotton in Texas which revealed that banded treatments outperformed broadcast applications of K with improvement in yield and return on investment.

Phosphorus is essential for life, and the input of P fertilizer is critical to the production of sufficient food, feed, fiber, and fuel to support a growing world population. Most modern P fertilizer is made from phosphate rock (PR), a nonrenewable natural resource. Over the past decade or so there has been concern that the world would soon deplete its PR resources, and face a catastrophic P shortage; however, recent and thorough estimates of world PR supply indicate that a P crisis is not imminent, and that the we will not soon run out of PR.

The article offers information on effects of the price of crops on the optimum fertilizer rate by illustrating the example of corn crop. It mentions an online Excel tool called as KSU-NPI_CropBudgets to estimate impact of prices of crop and the fertilizer used during cultivation on the nutrient application involving nitrogen and phosphorus. It concludes that farmers should analyze the agronomic data as per the maximum economic yield (MEY) program before reacting to the crop market.

The article offers updates related to fertilizer and food production. Demand for food worldwide is indicated to show a sharp increase due to 40% increase in population by 2050. Fertilizers are noted as undeniably important in production intensification and yield increase on limited arable land. Fertilizer input is stated as essential in meeting the escalating food needs worldwide.
