Book Description
"Although forage crops occupy the majority of agricultural land in Alaska, best fertilizer management practices to maximize forage yield and quality in Alaska are not well established. The objective of this study was to determine optimum time and rate of nitrogen (N) fertilizer applications to produce high yields of high quality forage in interior and Southcentral Alaska from smooth bromegrass (Bromus inermus). Nine N fertilization treatments, differing in rate and time of application, were applied at four sites. Forage samples were harvested twice per season in 1999 and 2000 to obtain yield and quality values. Nitrogen applied at 225 kg ha−1 produced greater yields than N applied at 125 kg ha−1, but there were no significant differences between single and split applications. Yield and crude protein content of the control were significantly lower than plots receiving N treatment. Midseason application of N increased crude protein percentages in second cuts at most sites. Acid and neutral detergent fiber were not affected by N treatment. N fertilizer use appeared to be more efficient for split applications, but no significant differences were found. This study showed potential for the production of high yielding, good quality grass forages in Alaska under a variety of N fertilizer strategies"--Leaf iii.

Book Description
There is a concern about the growing population and limitation in natural resources which are taking the population to direct its agricultural systems into a more productive and efficient activity, looking to avoid a negative impact on the surrounding environment. The industry energy expended to produce nitrogen (N)-fertilizer is considered an indirect consumption of energy in agriculture, which is higher with an increasing forage yield. Nitrogen is the key nutrient associated with high-yielding production in forage grass and grain crops. The aim of this chapter is to introduce the best management practices (BMPs) for N-fertilizer application in forage grasses to improve N-use efficiency, since the most economical way to feed livestock is forage plants where its potential biomass production is not well explored. The BMPs basically follow three management practices: (1) soil nutrient availability and forage requirement, (2) fertilizer application, and (3) decrease in nutrient losses from soil. In order to take a decision on applying N-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits, the N-fertilizer use in forage grasses is going to follow the "Right rate, Right source, Right place, and Right time (4R) nutrient stewardship." The application of the 4R's nutrients stewardship is directly associated with economic, social, and environmental impact. The capacity of the 4R's implementation worldwide turns into a best guide to improve the striving of better N-use efficiency in forage grass. The 4R's are interrelated; thus, the recommendation of N-fertilizer rates cannot be prescribed without the combination of the 4R's where a whole system to be followed should be considered to decide about N-fertilizer in pasture. Consequently, any decision in one of the 4R's is going to affect the expected N-fertilizer results and dry matter production.

Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
