“…It can be concluded from the above equation that the addition of organic carbon by 10% to obtain a field capacity (0.219 cm 3 cm -3 ) is higher by 50% compared to 0OC (0.146 cm 3 cm -3 ), and these ratios are important in increasing available water to the plant when it is invested. These results agree in their direction with the results of some researchers [16]. The loam soil gradually increased with a power function FC = 0.42 (OC%) 0.08 and a coefficient of determination (R 2 ) 0.97.…”

“…The most important thing is to use criteria such as soil health indicators that can be evaluated [2,8,9]. Many methods and processes were adopted to improve soil health such as using minimum tillage, crop rotation, cover crops, and adding organic fertilizers [10,11], and these characteristics have an important role in the capacity of water available for plants [12][13][14][15][16]. At the same time, soil organic carbon is an important and influential factor in many basic parameters of soil properties because it provides the support of biodiversity important in the formation and stability of Soil aggregates and related water relations.…”

An experiment was carried out to study the effect of soil organic carbon (SOC) and soil texture on the distance of the wetting front, cumulative water infiltration (I), infiltration rate (IR), saturated water conductivity (Ks), and water holding capacity (WHC). Three levels ( 0, 10, 20, and 30 g OC kg-1 ) from organic carbon (OC) were mixed with different soil materials sandy, loam, and clay texture soils. Field capacity (FC) and permanent wilting point (PWP) were estimated. Soil materials were placed in transparent plastic columns(12 cm soil column ), and water infiltration(I) was measured as a function of time, the distance of the wetting front and Ks. Results showed that advance wetting front as a function of time for soil column was 6 minutes and with no differences between OC levels for sandy soils, while it ranged between 90 minutes (0% OC) - 130 minutes (3% OC) for loam soils, and between 470 minutes (0 %OC) and 590 minutes (1%OC) for clay soils, at the same time cumulative water infiltration(I) increases at the beginning of infiltration and decreases with time and levels of OC. The highest infiltration values were in sandy soils, giving data of 0.05 and 0.12 cm min-1, with no significant differences with OC rates. IR values decreased when OC increased in loam soils, and IR increased exponentially in clay soils with increasing OC levels. The values of Ks decrease with increasing OC for sandy and loam soils, and increase when OC increases above 3% for clay soils. FC and WP values were increased for sandy, loam and clay soils when OC was increased. The AW values decreased for both sandy and clay soils compared to loam soils. It can be concluded that AW can be estimated from FC values regardless of texture and OC by the linear function: AW=0.51(FC)+0.005.

“…Soil health is defined by USDA‐NRCS as “the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans.” Soil health is often assessed by measuring properties indicative of a soil’s capacity to function. The Soil Health Institute has identified a minimum suite of indicators to quantify soil health in the top 6 inches of soil (Bagnall et al., 2023): Soil organic carbon concentration relates to the soil’s ability to cycle and retain nutrients, store water, and provide structure that supports other soil functions. Carbon mineralization potential quantifies the capacity to cycle carbon and nutrients by the soil microbial community. Aggregate stability indicates the capacity of soil to resist wind and water erosion, allow for water infiltration and storage, and provide a stable structure to support other soil functions. Available water‐holding capacity (AWHC) estimates the amount of water the soil can store and provide to plants. …”

“…Los indicadores biológicos, considerados indicadores tempranos, presentan elevada sensibilidad, son dinámicos y responden rápido al manejo del suelo agrícola (Bagnall et al, 2023). La BM interviene en la mineralización de la MO, proceso durante el cual se sintetizan y secretan aminoácidos, proteínas, aminoazúcares (por ejemplo, la glucosamina) (García y Rivero, 2012).…”

Los parámetros biológicos son usados como indicadores tempranos en la calidad de un suelo (ICS) agrícola, ya que responden rápidamente al manejo antrópico. El objetivo de esta investigación fue determinar el efecto del sistema de labranza: siembra directa (SD) y labranza convencional (LC), y de la fertilización nitrogenada después de los cultivos de fréjol y maíz, sobre ciertos indicadores biológicos de la calidad del suelo. El estudio se realizó sobre un molisol de la región andina del Ecuador. Se determinó la biomasa microbiana (BM), respiración microbiana (RM), y actividad enzimática (fosfatasa ácida, hidrólisis de la fluoresceína-diacetato [FDA], y β-glucosidasa [β-G]). Los resultados mostraron que la fosfatasa presentó la mayor actividad bajo LC, la FDA respondió al efecto de los niveles altos de nitrógeno (N), la actividad de la enzima β-G fue mayor en LC. Adicionalmente, el análisis de componentes principales seleccionó a los indicadores biológicos estudiados, como ICS. Se concluye que los indicadores biológicos del suelo fueron afectados por las prácticas de manejo estudiadas.
