nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

It was pointed out in a previous report (1) that the inorganic composition of the pulp of Fuerte avocado fruit varies according to the availability of fertilizer elements in orchard soils. Fullmer (2) has shown for these same orchards that the petioles (leaf stalks) and leaf blades from trees in orchards that have received fertilizers containing phosphorus and potassium tended to contain higher...

Batanghari Regency is one of the regencies in Jambi Province that has a potential for development lowland rice commodities. Rice farming consists organic and inorganic rice. Organic technique using fertilizer (compost fertilizers) can be broken down by decomposer organisms. The continuous use chemical fertilizers pesticides on agricultural land results decrease structure composition nutrients s...

Balanced nutrients are essential for healthy plant growth, but there is no sensor available to monitor such as N and K. Electrical conductivity (EC) one of the key parameters that could be adopted nutrient contents because soil EC influenced by nutrients. Therefore, main objective this study was examine effects different basal fertilizers, including inorganic, organic, compost application ratio...

Root crops are an important staple food in the Pacific region. Yields are generally low and inorganic fertilizers are deemed an option to increase root crop production. The effects of inorganic N fertilizers on upland taro (Colocasia esculenta (L.) Schott) and sweet potato (Ipomoea batatas (L.) Lam.) were quantified with the aim to investigate relationships between inherent soil fertility, N up...

After cut off of inflowing water, Lake Paro, an oligomesotrophic lake lost littoral zone, an important region for the aquatic ecosystem. For the first step of restoration, the artificial vegetation island was installed. The concentration of nutrients in lake water was not sufficient for the growth of macrophyte as total phosphate was ranged from 58 to 83 μg L(-1). In order to overcome this prob...

Hydroxylapatite – Ca5(PO4)3(OH) – is the main mineral in bones, giving them their compressive strength, and, as found in nature, is often called phosphate rock. Phosphate rock is commercial mined for its phosphorus, for use in fertilizers and other purposes. Its formation is sometimes used to remove phosphorus from wastewaters, including manures. It is often also known as hydroxyapatite (that i...

Upland rice is typically grown under slash-and-burn systems in the mountainous regions of northern Laos by resource-poor farmers for subsistence. Upland rice cultivars are all traditional and no fertilizer inputs are used. In these systems, grain yields average only 1.7 t/ha. A multi-site experiment was conducted in Luang Prabang province to examine cultivar and fertilizer effects on grain yiel...

Melioidosis is an often fatal infectious disease affecting humans and animals in tropical regions and is caused by the saprophytic environmental bacterium Burkholderia pseudomallei. Domestic gardens are not only a common source of exposure to soil and thus to B. pseudomallei, but they also have been found to contain more B. pseudomallei than other environments. In this study we addressed whethe...
