Book Synopsis Corn Crop Production by : Arn T. Danforth
Download or read book Corn Crop Production written by Arn T. Danforth and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn or maize is a crop that originated in Mexico and has spread all over the world as a major food crop. Sustainable production of a corn field crop as grain corn for feed, food and biofuels, as well as sweet corn for fresh market or processing, and as silage for high energy sources, requires scientific management of nutrients along with several other crop management practices such as proper plant population density, timely seeding and harvesting, soil water, weeds and pests control. Corn has become the major item in the diet of many tropical peoples, the main grain used for animal feed in temperate regions, as well as new stocks for many other purposes including recently used as feedstock for biofuels. Rapid expansion of grain based ethanol production in North America, has already caused concern about future food and feed supplies. This important book gathers the latest research from around the world in this dynamic field.

Book Synopsis Effect of Soil Test Values and Fertilization on Corn, Soybean and Wheat Tissue Phosphorus and Potassium Concentrations by : Phoo Pye Zone

This book was released on 2019 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tri-State Fertilization Recommendations were published in 1995 and have provided a framework for phosphorus (P) and potassium (K) nutrient management in field crops. Due to changing soil properties, management practices and advanced crop genetics, there is a need to reassess plant tissue analysis using current soil conditions and modern hybrids. The Tri-State Fertilizer Recommendations use early reproductive leaf nutrient concentrations as a diagnostic of crop nutrient status and grain nutrient concentrations are the basis of fertilizer rates to replace nutrients lost at crop harvest. An evaluation of these nutrient levels in grain and plant tissue samples are therefore important when revising fertilizer recommendations. The goal of this thesis was to evaluate the how crop nutrient levels, especially P and K, are influenced by key soil and management factors. Specific objectives of Chapter 1 were to determine the effects of i) soil test P and K levels and ii) P and K fertilization on early reproductive leaf and grain P and K concentration of corn, soybean and wheat. The specific objective of Chapter 2 was to report grain nutrient concentration and nutrient removal rates in corn, soybean and wheat in Ohio. On-farm P and K fertilizer strip trials in corn, soybean and wheat were conducted at 262 sites in 39 counties across Ohio from 2014 - 2018. At each site, experiments were conducted using a randomized complete block design with 3-4 replications with two treatments, a P or K fertilization treatment and a non-fertilized control. Routine soil nutrient analysis before fertilization, nutrient concentrations in leaves at early reproductive stages, grain yields and grain nutrient concentrations at harvest were measured at each trial. Key site management practices were also recorded through a survey. The effect of soil test P and K level on plant tissue nutrient concentrations was assessed by using regression analysis. Fertilization effects on tissue nutrient concentrations were examined using analysis of variance (ANOVA). Early reproductive leaf and grain P and K concentrations of corn, soybean and wheat generally increased as soil test P and K increased. However, the relationships between soil test levels and nutrient concentrations were weak (all R2

Book Synopsis Soil Fertility and Nutrient Management by : Roma Doshi
Download or read book Soil Fertility and Nutrient Management written by Roma Doshi and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil fertility refers to the ability of a soil to supply plant nutrients. Bioavailable phosphorus is the element in soil that is most often lacking. Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example a 10-10-15 fertilizer has 10 percent nitrogen. Inorganic fertilizers are generally less expensive and have higher concentrations of nutrients than organic fertilizers. Also, since nitrogen, phosphorus and potassium generally must be in the inorganic forms to be taken up by plants, inorganic fertilizers are generally immediately bioavailable to plants without modification. However, some have criticized the use of inorganic fertilizers, claiming that the water-soluble nitrogen doesn't provide for the long-term needs of the plant and creates water pollution.
