Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Design, Integration, and Experiment of Transplanting Robot for Early Plug Tray Seedling in a Plant Factory

AgriEngineering
In the context of plant factories relying on artificial light sources, energy consumption stands out as a significant cost factor. Implementing early seedling removal and replacement operations has the potential to enhance the yield per unit area and the

Design and development of three-row improved pull-type rice transplanter for small farmers

The Indian Journal of Agricultural Sciences, 2014
A pull-type transplanter was developed by improvising the functional components of existing six-row manual IRRI rice transplanter. The improved transplanter is capable of planting seedlings in three rows at 250 mm row spacing.

Germination and seedling establishment for hydroponics: The benefit of slant boards.

PLoS ONE, 2022
Germination and seedling establishment for transplanting into hydroponics often uses porous substrates, but fine roots grow into these substrates, and they cannot be removed without damaging these roots.

MODIFICATION OF SEMI-AUTOMATIC TRANSPLANTER FOR COTTON SEEDLINGS [PDF]

Misr Journal of Agricultural Engineering, 2015
The experiments were carried out during 2014 seasons at Sakha-farm research to evaluate performance of modification  transplanter for cotton seedling. The experiments were conducted using a modification transplanter to evaluate the effect of forward speed of 1.88, 2.35, 2.95 and 3.38 km/h, hill spacing of 0.15, 0.2, 0.25 and 0.3 m and planting depth of

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, EarlyView.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.

Biometric properties of onion seedlings relevant to the development of onion seedling transplanter

Journal of Applied and Natural Science, 2015
A study was conducted to investigate biometric properties of seedlings of three common varieties of onion viz. Pusa Red, Set-126 and Pusa Ridhi (50, 60, 70 days old). The parameters determined were weight of seedling without and with de-topping, bulb diameter, stem diameter, height, moisture content, compressive strength and coefficient of static ...

Breeding switchgrass for reduced nitrogen demand

Grassland Research, EarlyView.
Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

Journal of Plant Nutrition and Soil Science, EarlyView.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.

Wheat Wild Relatives and Modern Cultivars Differ for Salt Resistance in Terms of Morpho‐Physiological Traits

Journal of Plant Nutrition and Soil Science, EarlyView.
Wheat wild relatives are untapped genetic resources from salinity and drought hit areas. This study presents differential comparative morphophysiological responses of these species and modern wheat cultivars under saline conditions. Salt resistant species produce more shoot and root biomass under saline conditions through salt exclusion and/or tissue ...
