Book Synopsis Improving Potassium Recommendations for Agricultural Crops by : T. Scott Murrell
Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer. This book was released on 2022 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Book Synopsis Validation of Soil-test-based Phosphorus and Potassium Fertilizer Recommendations for Rice and Soybean by : Matthew Scott Fryer
Download or read book Validation of Soil-test-based Phosphorus and Potassium Fertilizer Recommendations for Rice and Soybean written by Matthew Scott Fryer and published by . This book was released on 2015 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of soil-testing for nutrient management and fertilizer recommendations is widely accepted among scientists and agronomists. Although this science is unsurpassed in predicting soil nutrient availability, soil-test interpretations are seldom validated. Major research objectives for irrigated soybean [Glycine max (L.) Merr.] and direct-seeded, delayed-flood rice (Oryza sativa L.) were to: i) validate the accuracy of Mehlich-3 soil-test P (STP) and K (STK) interpretations and ii) published critical tissue-P and -K interpretations in predicting the yield response to fertilizer at different significance levels (p≤0.05 to 0.25), iii) examine how seed nutrient concentrations are influenced by fertilization and crop response to fertilizer, and iv) evaluate how soil samples from two different depths (0-10 and 0-30 or -45 cm) influence crop response to fertilization. Seventeen (soybean) and 16 (rice) total field experiments were conducted in 2013 and 2014. Soil-P interpretations showed an overall accuracy of 40 (p≤0.05) to 55% (p≤0.25) for soybean and 35% (p≤0.05 and 0.25) for rice in predicting the yield response to fertilizer. Overall accuracy of STK interpretations regarding yield response predictions was 71 (p≤0.05) to 84% (p≤;0.25) for soybean and 14 (p≤0.25) to 20% (p≤0.05) for rice. Complete evaluation of critical tissue-P (soybean) and -K (rice) concentrations were unfeasible due to the lack of site-years in deficient categories. Rice tissue-P concentrations were 50 (p≤0.05) and 39% (p≤0.25) accurate in predicting the fertilizer effect on yield. Yield response to fertilizer was accurately predicted at 48 (p≤0.05) to 62% (p≤0.25) of the sites by tissue-K concentrations of soybean. Seed nutrient concentrations of soybean were influenced by fertilizer more frequently and to a greater measure compared with rice. Regression analysis of soil nutrient indices of the shallow and deep soil depths for both crops were relatively strong with a slope close to 1.0 suggesting nutrients at deeper depths had minimal effects on the yield response of either. With exception to STP in rice, nutrient concentration interpretations of soil and tissue for both crops and nutrients were affected by the significance level used to evaluate the data. Tissue concentrations were an inferior (soybean) and superior (rice) predictor of crop response to fertilizer.

Book Synopsis Sustainable Market Farming by : Pam Dawling
Download or read book Sustainable Market Farming written by Pam Dawling and published by New Society Publishers. This book was released on 2013-02-01 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing for 100 - the complete year-round guide for the small-scale market grower. Across North America, an agricultural renaissance is unfolding. A growing number of market gardeners are emerging to feed our appetite for organic, regional produce. But most of the available resources on food production are aimed at the backyard or hobby gardener who wants to supplement their family's diet with a few homegrown fruits and vegetables. Targeted at serious growers in every climate zone, Sustainable Market Farming is a comprehensive manual for small-scale farmers raising organic crops sustainably on a few acres. Informed by the author's extensive experience growing a wide variety of fresh, organic vegetables and fruit to feed the approximately one hundred members of Twin Oaks Community in central Virginia, this practical guide provides: Detailed profiles of a full range of crops, addressing sowing, cultivation, rotation, succession, common pests and diseases, and harvest and storage Information about new, efficient techniques, season extension, and disease resistant varieties Farm-specific business skills to help ensure a successful, profitable enterprise Whether you are a beginning market grower or an established enterprise seeking to improve your skills, Sustainable Market Farming is an invaluable resource and a timely book for the maturing local agriculture movement.
