Recent trend depicts that tomatoes and tomatoes products rank 2 most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2 in the United States in terms of production value, generating $1.3 billion after head lettuce that contributed $1.4 billion in the same time period. In 20...

Loss of soil organic carbon (SOC) can cause soil degradation, which may not only undermine soil productivity, but may also-affect environmental health. In China, a huge amount of crop residues is regularly removed from the fields, and therefore China’s agriculture depends on high levels of chemical fertilizer inputs. This paper aims to estimate the SOC storage in Chinese cropland, identify its ...

Accurate cropland maps at the global and local scales are crucial for scientists, government and nongovernment agencies, farmers and other stakeholders, particularly in food-insecure regions, such as Sub-Saharan Africa. In this study, we aim to qualify the crop classes of the MODIS Land Cover Product (LCP) in Sub-Saharan Africa using FAO (Food and Agricultural Organisation) and AGRHYMET (AGRicu...

Why might it be that low income countries would apply regulatory systems for agricultural biotechnology modeled after European standards, even though it means their poor farmers and consumers lose any potential gains in agricultural productivity and social welfare? Ten years of commercial use in the United States, Canada, Argentina, and Brazil have demonstrated that traits such as insect-resist...

Globally, estimating crop acreage and yield is one of the most critical issues that policy decision makers need for assessing annual productivity food supply. Nowadays, satellite remote sensing geographic information system (GIS) can enable estimation these production parameters over large areas. The present work aims to estimate wheat (Triticum aestivum) Maharajganj, Uttar Pradesh, India, usin...

I the past, agricultural markets have been well integrated. Markets for different energy commodities, especially liquid energy products, also have been tightly linked. But agricultural markets and energy markets have not been closely correlated. Table 1 contains partial correlation coefficients between pairwise prices (both levels and first differences) of corn, soybeans, crude oil, gasoline, a...
