The preflood nitrogen (N) fertilizer sets the yield potential of the rice cultivars being grown and thus, its management is critical to obtaining profitable rice grain yields. The objectives of this study were to evaluate the ammonia volatilization loss and impact on rice yield when urea, Agrotain®, and ammonium sulfate were applied preflood and a flood established at 1, 5, and 10 days after N ...

Fertigation is widely used in the new intensive olive orchards, although, there is not enough information for a rational management of this practice. Preliminary results of an fertigation experiment iniciated in 1999 in a mature olive orchard of the cultivar ‘Manzanilla de Sevilla’ are presented. Four treatments were established: T1(no fertilizer) and T2, T3 and T4, in which the trees received ...

The tomato leafminer, Tuta absoluta (Meyrick) is a devastating pest associated with tomato. In this study, effects of tomato plants treated with vermicompost (20, 40, and 60%), humic fertilizer (2, 4 and 6 g/kg soil) and plant growth promoting rhizobacteria (Pseudomonas fluorescens and Bacillus subtilis) were investigated on the life table parameters of T. absoluta in a growth chamber at 25 ± 2...

The application of hydrological and water quality models is an efficient approach to better understand the processes of environmental deterioration. This study evaluated the ability of the Annualized Agricultural Non-Point Source (AnnAGNPS) model to predict runoff, total nitrogen (TN) and total phosphorus (TP) loading in a typical small watershed of a hilly region near Taihu Lake, China. Runoff...

Agricultural phosphorus (P) use is intricately linked to food security and water quality. Globalization of agricultural systems and changing diets clearly alter these relationships, yet their specific influence on non-renewable P reserves is less certain. We assessed P fertilizer used for production of food crops, livestock and biofuels in the US agricultural system, explicitly comparing the do...

Long-term impacts of alternative citrus nitrogen and water management practices implemented at grower cooperator sites on the Central Florida Ridge were modeled using the nitrogen component of the Leaching Estimation and Chemistry Model (LEACHN). A bromide tracer test was conducted at one representative cooperator site to parameterize and validate the model. Following validation, 50-year simula...

The changing environment affects agriculture introducing sources of uncertainty. On the other hand, policies to cope with risks may have strong impacts on the environment. We evaluate the effects of public risk management programmes, such as subsidised crop insurance, fertilizer use and land allocation to crops. We implement a mathematical programming model of a representative wheat-tomato farm...

The increasing need for food production in subtropical regions likely translates to a need for additional plant nutrients. As a consequence, knowledge of world fertilizer nutrient reserves is of particular relevance to sustainable agriculture in the subtropics. The stewardship responsibilities of agriculture include the wise use of the raw materials from which commercial fertilizers are produce...
