Agrochemical Composition of a New Organo-Humic Fertilizer and the Response of Cucumber Plants to Various Application Rates on Sandy Soils
A new organo-humic fertilizer, produced by accelerated fermentation of poultry manure using the "PEATGEL+" preparation, has a near-neutral reaction, is rich in macro- and microelements, and is free from heavy metals, toxic compounds, and radionuclides. The application of this new organo-humic fertilizer to sandy soil at a rate of 30–45 t/ha has a positive effect on the growth and development of cucumber plants of the "Izyashchny" variety.

Allometric Formulas to Predict Haematostaphis barteri Biomass Above and Below Ground in Cameroon
This study used a destructive approach to develop species-specific allometric equations for H. barteri in Cameroon. A sample of 30 individuals was chopped, measured, and weighed, and six prediction models were created for leaves, branches, trunks, roots, and total above-ground biomass. The best models were chosen using Akaike's information criterion, residual standard error, root mean square error, and adjusted coefficients of determination. The total biomass above ground was ln (B) = 2.832…

Allometric Model for Predicting above Ground Carbon Stock of Gardénia Stands in Central Africa: A Case Study of Cameroon
Allometric equations estimating carbon stock of Gardenia aqualla and Gardenia ternifolia stands in Cameroon have been developed. The sample consists of 35 individuals of Gardenia aqualla and 35 individuals of Gardenia ternifolia. These individuals were cut, measured and weighed entirely and the data acquired was used to build predictive models of biomass as a function of diameter at breast height. Adjusted coefficients of determination, residual standard error, root mean square error and…
