Introduction The use of biosolids from wastewater treatment plants in agriculture is considered relevant for the promotion sustainable agricultural practices, improvement soil fertility, and reduction dependence on synthetic chemical products. Dominican Republic today world's largest producer organic bananas main exporter fair-trade to Europe. generated currently have no use. In other countries...

The community of milkfish cultivators who are members the "Sipakatau" cultivator group in Pangkep Regency, until now still has various kinds obstacles to increase its production. problem is related use chemical fertilizers before stocking seeds, aim fertilize growth klekap and other phytoplankton be used as natural food for young milkfish, so that it an impact on green blue algae produce geosmi...

The invention of technical N2 fixation (TNF) opened the way to fertilize urea, NH4+, NO3 plant demands surpassing. An enchased the production sites from the thermodynamic equilibrium moving away and yields significantly increasing soil organic matter (SOM) conversion promotes nitrification through NH4+ and CO2 availability in higher amounts. Mobile NO3 ions in access formed dislocate towards gr...

Competition between males to fertilize a female’s eggs can occur before, during, and after copulation (Parker, 1970; and see Birkhead & Møller, 1998). When the sperm of two or more males simultaneously occupies the reproductive tract of a female and competes to fertilize her eggs, sperm competition occurs (Parker, 1970). Sperm competition has been documented or inferred to exist in many species...

Use of mixed crop-livestock farms (MCLFs) is one of the oldest and most traditional farming methods practiced all over the world, and MCLFs are still one of the major systems of food production, particularly for organic foods. On these typically small farms, livestock are reared primarily on grass and naturally grown crops, while composted animal wastes are used to fertilize the soil for growin...

In Africa there is a need to increase food security especially in the dry season when livelihoods are most at risk. The fingerpond concept is designed to exploit fringe wetlands sustainably for food production whilst conserving swamp integrity and biological diversity. The concept is a marriage of natural wetland phenomena with the historic activities of riparian peoples and more recent agro-pi...

This thesis describes some interplays between the specification and the implementation of higher-order programming languages. We first investigate a traditional implementation of Scheme (compiler, run-time machine). We then turn to Action Semantics. And finally we cross-fertilize these two approaches using both syntax-directed and type-directed partial evaluation and introducing an alternative ...

Patchouli (Pogostemon cablin, benth) is one of the leading national commodities in form oil. Indonesia a tropical country, has high potential production plants. In order to obtain high- quality patchouli plants and production, it necessary fertilize planting medium, using mixture chicken manure rice husk charcoal as organic fertilizer can increase growth cablin Bent). The purpose this study was...
