Download or read book Impacts and Correction of Potassium Deficiency in No till and Strip till Soybean and Corn Production written by Shannon M. Blocker and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was initiated to determine if potassium (K) deficiencies seen in soybeans (Glycine max (L.) Merr.) under no-till and strip-till production systems are impacting soybean yields, and if so, what fertilizer application practices including: rate of K application; broadcast or deep band methods of application; and the use of starter fertilizer at planting; could be used to correct the problem. The residual impacts of K fertilization and placement were also evaluated on corn (Zea mays L.) grown in rotation with soybeans. This research was conducted on-farm in cooperation with local producers. Soybeans sites in 2007 were near Harris, Ottawa and Westphalia, Kansas with corn planted in 2008 at the sites near Ottawa and Westphalia. Soybean sites in 2008 were located near Ottawa and Welda, Kansas. Selected sites were generally near or below the current soil test K critical level of 130 mg per kg extractable K, based on sampling histories provided by the cooperators. Sampling in the spring of 2007 confirmed these soil test (ST) K levels. Soybean leaf tissue potassium levels in 2007 were less than the critical level of 17 mg per kg in the unfertilized control plots, and were significantly greater when potassium fertilizer was deep banded or a high-rate of K fertilizer was broadcast. No significant difference in yield of soybeans due to K fertilization was seen, likely due to significant water stress during the grain fill period, which severely limited soybean yield in 2007. Soil test K levels at all the research sites increased dramatically between 2007 and 2008, even where no K was applied. Different weather conditions experienced these two years may have contributed to this occurrence. No residual impacts of K fertilization in 2007 on soybeans were seen in soil tests, corn leaf tissue K levels or corn yield in 2008. Soybean sites in 2008 also showed a dramatic increase in K ST levels in 2008 as compared to farmer records. No effects of K fertilization on soybean growth or yield were seen in 2008. The 2008 Ottawa soybean site had very low P soil tests. A significant response to P fertilization contained in the starter treatments was observed. This suggests that the dominant farmer practice of applying P and K fertilizer to corn, and not applying fertilizer directly to soybeans, even at low soil test levels, may not be supplying adequate P to soybeans, and is likely costing farmers yields and profits.

Download or read book Nitrogen Fertilization in Soybean Under No Till Systems on the Straw written by Wander Luis Barbosa Borges and published by Eliva Press. This book was released on 2021-09-03 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil the cultivation of soybean is almost all done under no-till system, and the soybean is the Brazilian culture with fastest growing in the last three decades and corresponds to 49% of the grain planted area in Brazil. The increasing productivity is associated to technological advances, the management and efficiency of producers. Cultivated especially in the Midwest and South regions, soybean has established itself as one of the leading products of domestic agriculture and trade balance. Soybean was responsible for the formation of a complex structure of production, storage, processing and marketing in all countries where it is growing on a large scale. The great demand in the international market provided rapid expansion of this crop in Brazil, which occurred by the replacement of other cultures by soybean culture, and especially by the conquest of new agricultural frontiers. In relation to nitrogen fertilization efficiency in soybean crop, there are many doubts about the subject. In some situations, as in production systems under no-till with a high amount of straw on the soil, nitrogen fertilization can reduce the problem of nitrogen deficiency and also increase soybean crop yield, however, there is a limit of dose of nitrogen to be used and the soybean grain yield increase and the soybean price must compensate the nitrogen fertilization investment. This book will present results of researches conducted in the Northwest region of São Paulo State (Brazil), involving nitrogen fertilization in soybean under no-till system on the straw of sugarcane and on the straw of forage sorghum intercropped with Congo grass.

Download or read book Phosphorus and Potassium Management for Corn and Soybeans in Conservation Tillage written by Rogério Borges and published by . This book was released on 1998 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the grain yield, P or K uptake, and early dry weight responses of no-tilled and ridge tilled soybeans [Glicine max (L.) Merr.] and ridge tilled corn (Zea mays L.) to broadcast, deep-band, and planter-band P and K fertilizer placements under Iowa soil and weather conditions. Long-term P and K trials were established in 1994 at five research centers and were evaluated for four years. Forty short-term P-K trials were established in farmers' fields from 1995 to 1997. Treatments were various P (O to 56 kg P ha−1) and K (O to 132 kg K ha−1) rates broadcast, banded with the planter 5 cm beside and below the seeds, and deep-banded at a 15-20 cm depth before planting. Plant samples were taken at V5 to V6 growth stages, dried, weighed, ground, and analyzed for total P and K content. Soil samples were taken from different depth and position relative to crop rows or fertilizer bands.

Download or read book The Importance of Soil Organic Matter written by Alexandra Bot and published by Food & Agriculture Org.. This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
