| The nitrogen of organic fertilizers does not fully mineralize within a season, and hence will partly become available in later years. This effect is taken into account for the first year but generally not in later fertilizer applications. If it would be taken into account, fertilizer use could be more efficient. This study is an analysis of a 13-year field trial where crop yield was measured in 13 fertilizer treatments which differ in total N applied and decomposition rate. This is complemented with a model study in which mineralization and soil nitrogen content were calculated. We intended to show step by step that the use of fertilizers with a low decomposition rate, relative to fertilizers with a high decomposition rate, lead in the course of years to... |

| Comparing the decomposition of green tea as a fast -decomposing material with rooibos as a material, which is difficult to break down, allows for the calculation of the tea bag index. This provides information on the capability of the soil as a living organism to transform organic residues back into plant-available nutrients and make some contribution to the build-up of soil humus. This technique is easy to apply. Place the tea bag in the soil and take it out after three months to see how much is left. It is fascinating to discover the result of our hard working little helpers in the soil and how this work is giving nutrients to a new generation of plants.

| In the present study, AMF root colonisation of potato plants was compared between organically and minerally fertilised field plots, which did not significantly differ in the total amount of plant available P. The AMF root colonisation was increased in response to organic fertilisation. This indicates that organic fertilisation can enhance AMF development independently from the soil P fertilisation level. Furthermore, soil grown mycelium was trapped in fungal compartments. This technique allowed the extraction and quantification of coarse and finely branched soil grown hyphae after harvest. The soil in the fungal compartments was either fertilised with low or with high amounts of mineral P. In organically fertilised field plots, the amounts of finely... |

| Since 1980 a long-term experiment has been carried out to compare mineral fertilizers (MIN), composted manure (RM) and composted manure with application of biodynamic preparations (RMBD) at three different fertilizer application rates. The total C and N contents in the topsoil were significantly different between all three fertilizer types. 42.9 to 53.7 % of Nt was bound in 18 total hydrolysable protein amino acids (THAA) including asparagine and glutamine. Amino acid contents in the hydrolysates of the topsoil were significantly different according to fertilizer type: MIN < RM < RMBD. The higher contents in manure fertilized plots were observed even at the lowest rate of fertilizer application. This indicates that differences between the treatments... |

| Harvest index, which measures the economic harvest of a crop, often refers to that part of a crop representing that which can be eaten or sold to others for consumption; in smallholder farming. The remainder of the crop, referred to as crop residue; is either fed to livestock, used to build fences, used as mulch, ploughed in (where such equipments are available) or burnt in small-scale farming, causing environmental pollution. These crop residues are also rich in nutrients that were extracted from the soil, used in the building of the edible parts and contribute to soil mining if not returned to the soil. This is a major bottleneck among smallholders as harvesting could take place when the soil is too dry to turn easily or they may not have the labour to... |

| Aims: To assess the effect of organic waste and their formulations on the development of the black soldier fly larvae. Study Design: The experiment used one time feeding (lump feeding) of feedstocks obtained from organic market waste fractions and their combinations. The arrangement of composting containers followed a Randomized Complete Block Design (RCBD), replicated three times. Place and Duration of Study: The study took 3 months and was conducted at the BSF laboratory of the Soil and Environmental Science Research Centre, Biotechnology and Nuclear Agriculture Research Institute of the Ghana Atomic Energy Commission in Accra, Ghana, West Africa. Methodology: Two hundred and forty (240) hand counted 5 day old BSF larvae were inoculated onto 2 kg each... |

| O objetivo deste trabalho foi avaliar a dinâmica de acumulação de massa e nutrientes do milheto e aferir o estágio mais adequado para manejá-lo, a fim de possibilitar maior aporte de massa e nutrientes ao sistema solo, visando maximizar o seu potencial como adubo verde. O estudo foi desenvolvido em condições de campo em Dourados-MS num Latossolo Vermelho distroférrico, textura muito argilosa, e em Itaquiraí-MS num Latossolo Vermelho amarelo, textura arenosa, ambos em agroecossistema sob transição agroecológica. O milheto (cultivar BRS 1501) foi semeado de forma direta em Dourados e após preparo do solo através de uma gradagem pesada e uma de nivelamento, em Itaquiraí, ambos sem adubação. As semeaduras foram realizadas no período de outubro a novembro. Os... |

| Quality compost can have a positive effect on soil fertility and plant growth and health. This positive effect is not only observable in the laboratory, but also by growers. Phytopathological problems could be solved with the use of compost. Durable success can only be obtained if a quality management is resolutely followed. Further research is needed to optimize the quality management of compost production and utilization. For example, very little is known about the long-term effect of the different composts on soil fertility and disease receptivity. |

| The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)... |
