Book excerpt: Excerpt from Determining Profitable Use of Fertilizer Fertilizer has been important in increasing yields of crops and total farm output. Increases in yields brought about by use of more fertilizer have meant higher returns not only per acre, but also per hour of labor. For small farmers particularly, wise use of ferti lizers means a substantial increase in size of business. Overhead costs per acre are usually higher on small farms than on large ones. Therefore, in order for small farms to obtain the same net return per acre as large farms they have to obtain high yields. A knowledge of yield response at different rates and combinations is necessary in order to decide upon the most profitable application of fertilizer° 'widespread information of this type would guide farmers in making choices as to expenditures. In periods of declining prices, returns from.all expenditures are reduced, but it is particularly important to maintain the practices that contribute most to net returns. Farmers who have followed good practices, including profitable use of fertilizers, know about what yields represent the most profi table levels for their own farms, but they may not be aware of the effect of changes in prices and costs on rates that should be applied for maximmm.returns. Also, there are often different ways of reach ing these yieldso For example, different combinations of plant nutri ents may result in the same yield, but one combination may cost less per acre than another. This aspect of the most profitable use of fertilizer has general implications as well as implications for indi 'vidual farms. For example, if sulfur, which is used in the manufac ture of phosphate fertilizer, should cost more in the future relative to other materials used in manufacturing fertilizers than it has in the past, it might influence recommendations that should be made as to plant nutrient ratios for specific purposes. If, for example, more nitrogen and less phosphate will result in the same yield of a given crop, recommendations should reflect this fact if reserves of sulfur should become relatively short. Such questions as this can be answered only by adequate information as to yield response at different rates and combinations of plant nutrients. Economic interpretation can then provide answers as to the most profitable rates and combinations for any cr0p price-fertilizer cost relationship. It can also determine the least-cost combination at which to obtain a stated yield. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
