Book Synopsis Controlled-Release Fertilizers as a Means to Reduce Nitrogen Leaching and Runoff in Container-Grown Plant Production by : Jianjun Chen
Download or read book Controlled-Release Fertilizers as a Means to Reduce Nitrogen Leaching and Runoff in Container-Grown Plant Production written by Jianjun Chen and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Container-grown plants refer to plants produced in confined volume filled with substrates. The substrates endogenously have limited nutrients and low water-holding capacity. Plants grown in the containers must be fertilized and watered frequently varying from daily to weekly. Frequent fertilization and irrigation can result in nutrient leaching and/or runoff. Since nitrogen (N) is a key component of the majority of fertilizers, container plant production has been viewed as a source of N leaching and/or runoff. The leaching and runoff, if in large quantities on a year-round basis, could affect surface and ground water quality. Application of controlled-release fertilizers (CRFs) has been reported to have less N leaching than plants fertilized with water-soluble fertilizers (WSFs). However, there are different types of CRFs with different compositions and longevities on the market. Container plants also differ greatly in their growth and development and in N requirement. Thus, production of high-quality container plants with minimum N leaching using CRFs still remains challenging. This article is intended to discuss characteristics of container plant production and N leaching and runoff during production, and to document that CRF application can reduce N leaching and/or runoff. Certain requirements for future development of CRFs are also discussed.
Book Synopsis Nitrogen in Agriculture by : Khan Amanullah
Download or read book Nitrogen in Agriculture written by Khan Amanullah and published by BoD – Books on Demand. This book was released on 2018-02-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability. Efficient use of nitrogen for crop production is therefore very important for increasing grain yield, maximizing economic return and minimizing nitrous oxide (N2O) emission from the fields and nitrate (NO3) leaching to ground water. Integrated nitrogen management is a good strategy to improve plant growth, increase yield and yield components, grain quality and reduce environmental problems. Integrated nitrogen management (combined use of chemical + organic + bio-fertilizers) in field crop production is more resilient to climate change.

Book Synopsis Effects of Controlled-release Fertilizer on Nutrient Leaching and Garden Performance of Impatiens Walleriana (Hook. F. 'Xtreme Scarlet') by : Gladys Anguti Andiru
Download or read book Effects of Controlled-release Fertilizer on Nutrient Leaching and Garden Performance of Impatiens Walleriana (Hook. F. 'Xtreme Scarlet') written by Gladys Anguti Andiru and published by . This book was released on 2010 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis describes the effects of controlled-release fertilizers (CRF) of different formulations and longevities on nutrient leaching out of the containers and garden performance of Impatiens walleriana. In the first experiment, impatiens plants were grown with Osmocote Plus 16-9-12 formulation of 5-6 month (5-6M) and 8-9 month (8-9M) longevities placed at four positions in the container: Topdressed, Incorporated, Top-one-third and Bottom. A 150 mgL−1 N Peter's Professional water-soluble fertilizer (WSF) of 20-10-20 formulation was used as a control. Leachates were collected at every irrigation and the concentrations of N, P, and Fe in the leachates were measured. Shoot dry weight (DW) and canopy cover (CC) were also measured. Total amount of water leached and nutrients lost from CRF and WSF were quantified. WSF produced plants of similar quality as CRF treatments except when CRF was applied at the bottom of the container. This fertilizer placement resulted in plants with the lowest DW, CC and leached the most P and Fe. CRF applied as topdressed leached the highest amount of N. Irrigating with a known volume of WSF solution leached less N and P but more Fe than 5-6M treatment. The WSF leached similar amount of nutrients as 8-9M CRF. In a second experiment with the same fertilizers, the amounts of water, N, P and Fe leached or lost out of the containers during irrigation with a hose were quantified. Irrigating plants with a hose caused up to 62% more water loss and up to 95% more nutrient loss during irrigation with WSF than CRF. In a third experiment, Osmocote Plus 15-9-12 of 3-4, 5-6, 8-9 and 12-14 month longevities were applied at rates of 1.4, 3.4, 6.8, 10.2 and 13.6 kgm−3. The same WSF as in the first experiment was used as a control. Impatiens plants were grown in the greenhouse and consumer evaluations were performed. Plant CC, flower cover (FC) and DW were determined. Commercially acceptable plant quality was achieved with CRF application rates between 3.4 - 6.8 kgm−3. The aesthetic value of plants was not affected by the differences in DW, FC or CC. In experiment four, the same treatments as in experiment 1 were used with the addition of a treatment of a 50 - 50% blend of 5-6M and 8-9M. Impatiens plants were grown in the greenhouse and transplanted in the field where no fertilizer was applied. DW, consumer ratings (CR) and leaf greenness (LG) were obtained. Plants grown with CRF performed better in the field than WSF grown plants. CRF treated plants were less chlorotic, had greater DW and CR in the field. Based on our study, the standard 8-9M longevity CRF at medium rates resulted in lower N, P and Fe losses, and plants with increased DW, high CC and FC. Further work with other species is necessary to validate the results obtained with impatiens. However, at least for impatiens and under our experimental conditions, standard 8-9M longevity CRF at medium rates seems to be the best option.
