This book was released on 2019 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the recent studies focus on the consequences of extreme weather on crop yields, especially on droughts and hot weather. However, knowledge of the consequences of excess precipitation on crop yield and subsequent consequences on the food production system is lacking. Therefore, we attempted to fill that knowledge gap. In this study, we collected historical crop yield data for Texas by county for grain sorghum and the historical daily precipitation data from weather stations within the county. The precipitation data (from the nearest station(s) to the cultivated area) and crop yield data were shortlisted (based on length of record and absence of missing values) and arranged for the period 1973-2003 covering a variety of crop growing seasons. Grain sorghum crop growing periods in different parts of Texas was estimated based on the east-west precipitation gradient, north-south temperature gradient, and typical planting and harvest dates in Texas. Using the daily time series of precipitation data, we estimated the growing season total precipitation and maximum 4-day total precipitation for each county growing rainfed grain sorghum. Using the two parameters mentioned above as independent variables, and crop yield of sorghum as the dependent variable, we tried to find out relationships between excess precipitation and decreases in crop yields using both graphical and mathematical relationships. Results were analyzed in four different levels 1. Storm by storm consequences on crop yield; 2. Growing season total precipitation and crop yield; 3. Maximum 4-day precipitation and crop yield; and 4. Multiple linear regression of independent variables (Growing season total precipitation and maximum 4-day precipitation and crop yield) and dependent variable (yield of rainfed grain sorghum) with and without a principal component analysis (to remove the relationship between confounding independent variables). Our graphical and mathematical results point out excess precipitation can decrease rainfed sorghum yields in Texas. Our results also suggest the rainfed sorghum yield reductions by excess precipitation can range from 18 to 38%.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.
