The various types of organic fertilizer can come from plant, animal or mineral sources, depending on what chemicals your garden requires. Application of organic fertilizers to ponds depends on the fertilizer form and moisture content. The NH4-N, NO3 and chemical oxygen demand (COD) were all increased with increasing fertilization rates. Specifically, the effects of OA practices on SOC stocks depend on climate, soil conditions, soil erosion rates, grazing systems, and water and nutrient management. The animal's diet, the use and type of bedding material, manure age, and how it was stored are factors that affect manure nutrient value; these factors can vary seasonally on and among farms, and regionally or on a larger geographic scale. The nutrient content of organic fertilizers varies greatly among source materials, and readily biodegradable materials make better nutrient sources. Nutrients are concentrated in industrial processes to make them more available to plants. (1993) found that the addition of urea and triple superphosphate (TSP) into Nile tilapia ponds increased N and P inputs in the ponds and improved primary productivity, while the addition of chicken manure to these inorganic fertilizers did not enhance fish yield. High-quality organic fertilizers are the products of natural decomposition and are easy for plants to digest. Also through respiration, the bacterial population consumes oxygen and heavy applications of organic matter can result in low predawn pond dissolved oxygen concentration (Qin et al., 1995). Gypsum is a soil additive that helps to loosen compacted soil and promote root growth while enriching the soil with calcium and sulfur. (1990, 2002); Green (1992). Recently Manyi-Loh et al. However, some controversial data have been published that slurries could be a source of HM contamination because continuous application of heavy metal–loaded biogass slurry could result in an accumulation of HMs in soil (Bolan et al., 2003; Bian et al., 2016).

This is achieved by avoiding the use of synthetic fertilizers and pesticides, and using products that nurture your garden soil and the organisms in it. Synthetic fertilizers don’t enhance soil life or add organic matter. Diana (2012) suggested that animal manures should be used for the basic productivity, while nitrogen or phosphorus can be added as needed to gain nutrient balance in the pond. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost. However, this scenario may not be easily applied in some countries. (1978) found that chicken manure was not a very effective fertilizer in blue tilapia ponds in El-Salvador, and the addition of inorganic P (but not N) increased fish yields. Feed and fertilization strategies suggested for optimum yield of tilapia in semi-intensive culture systems (O. n = Oreochromis niloticus). K. Lorenz, R. Lal, in Advances in Agronomy, 2016. Addition of slurry results in enhanced precipitation, complexation, and adsorption of Cd, which ultimately reduces the bioavailability of Cd in the soil–plant system (Ahmad et al., 2015). Produced phytoplankton provides oxygen for respiration of aerobic organisms present in the pond. Since yields under OA systems are lower, direct soil C inputs are also lower compared to those under conventional systems. Animal manures are also better applied in tilapia ponds in fine particulate or colloidal state. Organic fertilizers can range from organic compost to cow manure, but they must be derived from all-organic sources. Weekly fertilization produced best growth. longifolia Lam. Like the developed countries, the digestion of organic waste for bioenergy production is also a widely accepted technique in developing countries. Therefore, buffalo manure rate should not exceed 50 kg ha−1 per day (Edwards et al., 1994a). Similar results were also reported by Huang et al. Rasnake et al. Organic fertilizers usually contain plant nutrients in low concentrations - grow organic vegetables. During the winter months, as outdoor gardens and flower beds sit dormant, many gardeners truly miss tending to and nurturing their plants. The effectiveness of fertilization depends on type and composition of fertilizer (Table 5.1), culture systems (monoculture vs. polyculture), fish species and species combinations, stocking size and density and environmental conditions. cv. that occurred between day 9 and 14, but a similar 1-log reduction of these cells during the rest of the process indicating a 90%–99% kill rate was achieved in mesophilic anaerobic digestion. (2006) who explored the trophic structure in organically fertilized and feed-supplied Nile tilapia ponds using multivariate analyses. Different organic fertilizers are presently used for organic apple production in the region of Trentino Alto Adige, which is particularly well suited to the growing of high-quality fruit and currently provides more than 60% of apple production in Italy. Generally speaking, a fertilizing rate of <100 kg ha−1 d−1 of poultry manure increases phytoplankton productivity and improves fish production (see Table 5.1). What are Organic Fertilizers? Indeed, the types and quantities of nutrients required and the relative amounts of fertilizers needed to provide such nutrients are varying, depending on the type of fertilizer used, nutrient contents of the water, types of bottom soil, water quality, environmental climatic conditions and geographical location.
