The current paper presents the monitoring of soil and nutrient losses through runoff as the result of the climate change. The experimental results were recorded on the standard plots for runoff and erosion control. The results of the studies carried out highlight that total nitrogen losses range from 0.05 kg/ha to 12.60 kg/ha, potassium displaced from the plots has values between 0.02 and 1.35 kg/ha, the humus associated with the eroded soil includes values between 0.51 and 176.5 kg/ha, phosphorus is recorded with maximum values of 0.39 kg/ha, the total iron losses have values between 3.14 and 431.16 g/ha, manganese has losses from 1.69 to 290.82 g/ha, copper losses range from 0.15 to 7.62 g/ha, and, regarding zinc, the values are within the limits of 0.25–57.22 g/ha. The maximum values of the displacement of fertilizing elements from the sloping agricultural lands, by means of liquid and solid leaks, are registered at the plots left as permanent black fields, the plots practically unprotected against the rain erosion. The experiments were performed at the Soil Erosion Research and Development Station “Mircea Moțoc”, Perieni/Staţiunea de Cercetare Dezvoltare pentru Combaterea Eroziunii Solului “Mircea Moţoc”, Perieni (SCDCES—MM, Perieni), Vaslui County, an institution strategically located in an area subject to erosion soil. Additionally, the paper envisages how the National Rural Development Programme (NRDP) and the Common Agricultural Policy (CAP) can be of use in this area by analysing past lessons and providing an overview of what was done.

The credit rating aims to establish the favorability classes of land for different agricultural crops. In this context, the present study aims to quantify the favorability of the Chromic Luvisols from S.C. Agrotehnic Paulesti for arable use. Also, this study has as a main objective a morphological characterization and profile description of Chromic Luvisols. Following the study, it can be concluded that it is presents the same limiting factors as for arable suitability related to the loamy-clay texture, which implies a short interval of soil works and the appearance of the hardpan sub-horizon.

The increasing need to identify sustainable nutrient sources and reduce dependence on mineral fertilizers has intensified interest in organic materials derived from residual waste streams. This study evaluates several unconventional foliar fertilizers formulated from wheat bran, cornmeal, vinasse residue, bone glue and defatted sunflower meal, aiming to enhance plant nutrition. Chemical analyses of the concentrates revealed substantial macronutrient contents, with nitrogen ranging from 73.78 to 103.8 g/l, phosphorus from 14.48 to 18.09 g/l and potassium from 31.28 to 48.79 g/l, together with high levels of essential micronutrients such as manganese (545–1200 ppm) and iron (325–695 ppm). Field experiments conducted at the SCDA Podu Iloaiei on wheat and maize demonstrated significant yield responses across all tested variants. Wheat yields increased by 320–1040 kg/ha, while maize yields rose by 470–1240 kg/ha compared with foliar-unfertilized controls. Fertilizers based on wheat bran and cornmeal achieved the highest specific productivity, reaching up to 115.55 kg grain per liter in wheat and 82.66 kg per liter in maize. Additionally, nutrient-use efficiency improved by at least 20%, accompanied by a similar reduction in environmental pollution. These findings support the agronomic relevance and ecological benefits of integrating waste-derived fertilizers into sustainable crop management systems.
