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...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...

ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...

The composting industry has been growing rapidly in China because of a boom in the animal industry. Therefore, a rapid and accurate assessment of the quality of commercial organic fertilizers is of the utmost importance. In this study, a novel technique that combines near infrared (NIR) spectroscopy with partial least squares (PLS) analysis is developed for rapidly and accurately assessing comm...

Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...

We studied the heterogeneity of soil weed seed-bank in a rice-wheat rotation system after long-term application of different organic or non-organic fertilizers, and the effects of major nutrients on the characteristics of the weed seed-bank. The soil was sampled in the Taihu area after a 31-year long-term fertilization experiment. Weed seeds were identified and counted in the surface soil of 12...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

The word organic, applied to fertilizers, indicates that the nutrients are derived from the remains or by‐products of a once‐living organism. Farmers are continually searching for alternatives to synthetic inorganic fertilizers to alleviate the escalating production costs associated with the increasing costs of energy and fertilizers and the problems of soil and surface water deterioration asso...
