Agriculture is a resource-intensive enterprise. The manner in which food production systems utilize resources has large influence on environmental quality. To evaluate prospects for conserving natural while meeting increased demand cereals, we interpret recent trends and future trajectories crop yields, land nitrogen fertilizer use, carbon sequestration, greenhouse gas emissions to identify key issues challenges. Based this assessment, conclude that avoiding expansion of cultivation into...
Data from farmer-managed fields have not been used previously to disentangle the impacts of daily minimum and maximum temperatures solar radiation on rice yields in tropical/subtropical Asia. We a multiple regression model analyze data 227 intensively managed irrigated farms six important rice-producing countries. The farm-level detail, observed over growing seasons, enabled us construct farm-specific weather variables, control for unobserved factors that either were unique each farm but did...

Soil property and class maps for the continent of Africa were so far only available at very generalised scales, with many countries not mapped all. Thanks to an increasing quantity availability soil samples collected field point locations by various government and/or NGO funded projects, it is now possible produce detailed pan-African nutrients, including micro-nutrients fine spatial resolutions. In this paper we describe production a 30 m resolution Information System African using, date,...
Abstract Southeast Asia is a major rice-producing region with high level of internal consumption and accounting for 40% global rice exports. Limited land resources, climate change yield stagnation during recent years have once again raised concerns about the capacity to remain as large net exporter. Here we use modelling approach map gaps assess production potential exports by 2040. We find that average gap represents 48% estimate region, but there are substantial differences among...
Understanding how much inorganic fertilizer (referred to as fertilizer) is applied different crops at national, regional and global levels an essential component of consumption analysis demand projection. Good information on use by crop (FUBC) rarely available because it difficult collect time-consuming process validate. To fill this gap, a first FUBC report was published in 1992 for the 1990/1991 period, based expert survey conducted jointly Food Agriculture Organization (FAO) UN,...
Abstract. Nutrient budgets help to identify the excess or insufficient use of fertilizers and other nutrient sources in agriculture. They allow for calculation indicators, such as balance (surplus if positive deficit negative) efficiency, that monitor agricultural productivity sustainability across world. We present a global database country-level budget estimates nitrogen (N), phosphorus (P) potassium (K) on cropland. The database, disseminated FAOSTAT, is meant provide reference,...
Accurate measurement of crop growth and radiation use efficiency (RUE) under optimal conditions is required to predict plant dry matter accumulation grain yield near the genetic potential. Research was conducted quantify biomass leaf area index (LAI) accumulation, extinction coefficient, RUE maize ( Zea mays L.) growth. Maize grown in two environments over five growing seasons (1998–2002). Total aboveground at maturity ranged from 2257 g m −2 1998 2916 2001; values that are considerably...
Abstract Crop intensification is often thought to increase greenhouse gas (GHG) emissions, but studies in which crop management optimized exploit yield potential are rare. We conducted a field study eastern Nebraska, USA quantify GHG changes soil organic carbon (SOC) and the net global warming (GWP) four irrigated systems: continuous maize with recommended best practices (CC‐rec) or intensive (CC‐int) maize–soybean rotation (CS‐rec) (CS‐int). Grain yields of soybean were generally within...
