These findings highlight the need to maintain, and where possible increase, organic carbon inputs into these farming systems which are rapidly becoming inorganic fertilizer intensive.
The organic farms in this study appear to have been intensively managed, with a straight substitution of organic inputs for chemicals, but little other effort to enhance soil fertility.
Based on these results, we conclude that the plant supply of organic matter primarily controls gross N mineralization and microbial respiration, but that the concentration of N in organic matter input secondarily influences these processes.
Long-term organic fertilization may control the accumulation of organic matter in subsoil.
They may be favoured by an organic input with a significant contribution of terrestrial, rather low quality organic matter.
This study shows the ameliorative effect of organic matter addition in ASS.
The study indicated only small changes in soil properties and stabilization of organic matter as a result of different detritus inputs.
This can be done by introducing organic matter with the help of specialized equipment.
For example, regular applications of organic residues will induce a long-term increase in soil organic matter content.
A further benefit of this strategy is an increase in soil organic matter.
To improve soil fertility, efforts need to be made to increase soil organic matter content.
As soil organic matter is primarily plant-derived, increases in POM-C reflect increased organic matter inputs or decreases in the rate of decomposition from the cessation of tillage.
The results indicate that additions of organic matter from various sources differ in the effects on soil organic matter and biological activity.
These results indicate that the organic matter-related resources mar...
We conclude that two pathways yield soil organic matter efficiently.

What is the ralation betwwen vegetation and artropods microhabitat ?
5 answers
The relationship between vegetation and microarthropod habitats is crucial for various ecosystems. Vegetation plays a significant role in providing habitats for microarthropods like springtails, mites, beetles, and others. In arid ecosystems, biological soil crusts interact closely with microarthropod communities, aiding in the decomposition of organic matter. The composition and density of vegetation are vital indicators for reptile habitats, affecting microhabitat use by different species. Changes in soil fertility and plant productivity influence the diversity and density of soil microarthropods, with more fertile sites harboring a greater proportion of predators. Microarthropods, such as Acari and Collembola, contribute to primary productivity in nutrient-poor conditions and can impact nutrient mobilization at the microhabitat scale.
How long does the adult stage of the black soldier fly last?
5 answers
The adult stage of the black soldier fly (Hermetia illucens) lasts for varying durations based on different studies. Research conducted in Bangladesh reported that the total life cycle of male and female black soldier flies ranged from 47 to 120 days, with females having a longer adult stage compared to males. Additionally, a study focusing on the influence of organic wastes on black soldier fly development found that the adult pre-oviposition period (APOP) and total pre-oviposition period (TPOP) were observed to estimate the performance of BSF on different organic wastes, indicating variations in the adult stage duration based on diet. Furthermore, an experiment in Kenya highlighted that the longevity of adult black soldier flies decreased with increasing temperatures, affecting the duration of the adult stage.
Why are banana peels and eggshells considered natural alternatives to synthetic fertilizers for spring onions?
4 answers
Banana peels and eggshells are considered natural alternatives to synthetic fertilizers for spring onions due to their nutrient characteristics and plant growth regulator (PGR) content. Banana peels, along with other organic wastes like moringa leaves and onion peels, meet the liquid organic fertilizer (LOF) standard for nitrogen content and have the potential to enhance plant growth. Eggshells, on the other hand, are rich in calcium, making them beneficial for plant development. Additionally, the production of organic fertilizers from banana peels, such as 'Potilizer,' aims to address food waste issues and promote sustainable farming practices, offering a natural and affordable option for farmers and gardeners. These natural fertilizers derived from plant waste provide essential nutrients and minerals without the negative environmental impacts associated with synthetic fertilizers.
