“…= 0.39), on the contrary, comparing only chicken manure doses (including the control), the increase in one unit in the dose didn´t cause a significant effect on the Pw (p>5%), this results shows that the application of 2.65 kg/m² of chicken manure is the best among all treatments based on chicken manure doses. Similar results were obtained in other studies aimed to evaluate the effects of the application of different organic fertilizers for production organic onions [27], [28]. The highest bulb yield recorded with application of chicken manure may be due to the supply of optimum amount of required for plant growth and development, coupled with improved soil physical and chemical condition.…”

In recent years awareness of the impacts of intensive agriculture on soil quality and its impacts on the environment has increased. This paradigm increased interest in biological products. In this context, the present trial was conducted to evaluate the performance of two organic fertilizers on onion and turnip crop yield grown in greenhouse. We used two kinds of organic fertilizers made in Portugal, a compost and a chicken manure evaluated in two plant species: onion (Allium cepa L.) and turnip (Brassica rapa L.). Both experiments consisted in a completely randomized design, with the same treatments which are: control (zero application), 1 kg/m2 of compost, 2 kg/m2 of compost, 3 kg/m2 of compost, 5 kg/m2 of compost, 2.65 kg/m2 of chicken manure, 5.3 kg/m2 of chicken manure, 10 kg/m2 of chicken manure, 15.9 kg/m2 of chicken manure, 21.2 kg/m2 of chicken manure. For turnip the evaluated traits were plant weight (Pw), plants length (Pl), number of leaves, and for onion were as follows: plant weight, bulb yields, and bulbs diameter. This study concludes that chicken manure in the dose of 2.65 kg/m2 application represents a sustainable alternative to synthetic fertilizers, mainly in the current challenging situation of agriculture in the context of climate change.

“…Baldantoni et al (2018) reported that in Mediterranean soils with poor soil organic materials (SOM), long-term biowaste compost fertilization experiment increases the quality of bulb yield. Similarly, other studies reported that application of 30 t ha -1 of beef manure compost increased onion bulb yield, Mg and K contents in loam and silty loam soils in southeastern Korea (Lee et al 2018a;Lee et al 2018b).…”

<p>True shallot seed (<em>Allium cepa var Aggregatum group</em>) is an alternative way of growing shallot. Different environments and cultivars need a specific study. The aim of this research was to find out the best technology to grow Trisula true shallot seed by managing plant densities and applying compost and biofertilizer in alluvial soils. The study was performed from May to October 2015, using a split-plot design with four replications. The main plot was plant density: 100 plants m-2 and 70 plants m-2. Subplots were five fertilizer application combinations, they were 100% recommended dose of NPK (R-NPK), 100% R-NPK + compost, 100% R-NPK + compost + biofertilizer, 50% R-NPK + compost and 50% R-NPK + compost + biofertilizer. Results showed that biomass and bulb yield were significantly affected by plant density and fertilizer application. The reduced 50% R-NPK by substituting with compost and biofertilizer was unable to maintain shallot bulb yield equal to 100% R-NPK, suggesting insufficient nutrients derived from compost to satisfy the shallot requirement. The best technology to grow true shallot seed of Trisula variety was 100 plants m-2 plant density and 100% NPK (consisting of 180 kg N ha-1, 52 kg P ha-1 and 50 kg K ha-1) with 2.5 t ha-1 compost that achieved the highest bulb yield of 9.83 t ha-1 and increased the revenue.</p>

“…Peat moss had an organic matter content of approximately 80%, whereas PMS contained approximately 50% organic matter. Organic matter in PMS can improve soil fertility by enhancing soil structure, water-holding capacity, nutrient availability, and microbial activity, leading to improved plant growth [1,5,7].…”

Potential Use of Paper Mill Sludge in Improving Soil Quality for Plant Growth

This study evaluated the impact of soil modifiers on seed germination and soil quality. Mixtures of paper mill sludge (PMS) with camellia oilseed cake (CO) and peat moss (P), as well as with oilseed cake of toothache tree (TO) and peat moss (P), showed promising results as biostimulants for seed germination. The addition of PMS increased the germination index, indicating its beneficial effects on seed performance. The pH levels remained optimal, and the electrical conductivity values stayed within acceptable ranges, suggesting minimal hindrance to plant growth. The cation exchange capacity increased with PMS, enhancing nutrient availability. Composted mixtures exhibited increased phosphorus levels, contributing to soil fertility. While the organic matter content decreased after composting, the carbon-to-nitrogen ratio remained balanced. The bulk density increased after composting, potentially improving soil drainage. Overall, the TO-containing mixture demonstrated superior growth rates compared to the P. These findings support the use of PMS-based soil modifiers for enhancing seed germination and improving soil quality.
