“…The literature indicates that when the soil water content increases from dry to water-saturated soil conditions, ions previously adsorbed are released from the soil particle surface. These released ions promote the decrease of electrical resistivity that is obtained from ERT surveys [8,39,[53][54][55] pH values show a significant positive correlation (R = 0.754; p < 0.01), (R = 0.777; p < 0.01), as is observed in the SP1, where the values slightly decrease with the alkalinity value.…”

In Spain, livestock farming is a significant activity area that generates substantial revenues and essential jobs. However, the actual impact that this intensive activity might have on the environment is not entirely understood. Moreover, coastal aquifers are subjected to a significant environmental pressure due to nearby growing population, intensive agriculture, and livestock farming. In this work, three representative pig slurry ponds, under semiarid conditions, were studied using different techniques to evaluate the subsurface conditions in terms of pH, electrical conductivity, salts, and nitrate content. The electrical resistivity tomography (ERT) technique was employed in this study, which provides electrical resistivity values from the subsurface materials and fluids. These electrical resistivity values were compared to data obtained from geochemical analyses to derive their relationships and establish the pig slurry-affected subsurface area. Thus, ERT-based lower electrical resistivity values were associated with higher salts concentrations and nitrate content. ERT values indicated a near-surface affected by slurry infiltration that coincided with the increase of geochemical values obtained from sample analyses. Additionally, Spearman’s correlation was used to evaluate the correlation between electrical resistivity data and the physical-chemical properties of soil. The most important pollutant accumulation mainly occurs in the two-meter depth. Therefore, the risk of slurry ponds affecting deep aquifers is limited in the studied area. Finally, this study proves a complete, affordable, and scalable methodology application to livestock residue storage facilities.

“…También se presentó una buena solubilidad del P en el contenido del biol con altos contenidos de P, CE, Ca, Mg ya que se originan de fuentes fosfatadas como la roca fosfórica, dolomita y la dieta de sales del ganado vacuno (Kongor et al, 2019). En este sentido Dionisi et al, (2020) reportó valores similares de CE a los de este estudio de un biol elaborado con residuos porcinos que estuvieron en función de la dieta alimenticia.…”

Se evaluó la calidad y eficiencia de un biol elaborado a partir de residuos de cosecha de cacao sobre un clon de cacao fino de aroma (TSH-565) en una parcela con arreglo agroforestal, ubicada en el distrito de Campo Verde, región Ucayali. Se utilizó un diseño de bloques completos al azar con tres repeticiones y cinco tratamientos aplicados a nivel de copa de árbol. El tratamiento control consistió en una única aplicación de la fertilización que realiza el productor de 1 kg de gallinaza, 250 g roca fosfórica y 250 g de dolomita, el T1 en la aplicación de biol diluido en agua a una concentración de 10%, T2 al 15%, T3 al 20% y para el T4 se combinó biol al 15% adicionando la fertilización del productor. El biol elaborado posee un alto contenido nutricional de macro y micronutrientes (N, P, K, Ca, Mg), salinidad y huminas. El contenido de N y K en el suelo no evidenció una variación considerable entre tratamientos, a excepción del P donde si se observó incrementos. En temporada de sequía solo variables de peso, diámetro (T1 y T2) y cantidad de mazorcas (T4 y T2) fueron significativamente superiores (P<0,05). Con el inicio de lluvias no se evidenció efectos residuales significativos. Los rendimientos más altos para grano seco fueron obtenidos en T1 (366 kg ha-1) y T2 (380 kg ha-1), siendo el más bajo el control con 185 kg ha-1 respectivamente.

“…Sugar beet vinasse and slurry may increase salt concentrations in the soil (Moran-Salazar et al, 2016;Dionisi et al, 2020), as does the excessive application of manure (Yilmaz and Alagöz, 2010). Even though these materials were used in our study, we did not notice any significant difference in EC depending on the sampling year or farm management, probably due to the salt leaching after rainfall events.…”

Agricultural management affects soil fertility through the frequency and type of agronomic practices such as mechanical operations, type and rate of fertilizers, crop rotations, and residue management. This study evaluated the evolution of soil chemical properties (pH; electrical conductivity; soil organic carbon, SOC; total Kjeldahl nitrogen, TKN; and available phosphorous, PO4-P) over time in two farming systems, organically and conventionally managed, after 5 and 14 years after the establishment of both systems, in northeastern Italy. SOC content remained stable in the conventional farming system, but slightly decreased in the organic farming system, despite inputs from organic amendments. In contrast, soil TKN remained consistently higher in the organic farming system. The PO4-P increased over time, in both farming systems. Moreover, we observed that an increase of 1% in soil clay content resulted in increases of 0.0534 and 0.0053 g kg–1 in SOC and TKN, respectively. In conclusion, our results indicate that organic management does not have an advantage over conventional management in terms of soil organic matter accumulation. Highlights - Organic management did not increase soil organic carbon content 14 years after the system was established. - The soil organic carbon was stable over time in the conventional system. - Soil organic nitrogen was higher in the organic farm than in the conventional farm. - Soil C/N ratios in organic and conventional management were <10, indicating active mineralization.
