“…Los tratamientos que contienen botón de oro igualmente presentaron mayor contenido de sílice, mineral que favorece a los vegetales contra el ataque de insectos y microorganismos patógenos, lo cual concuerda con lo afirmado por [13] quien dice que la sílice crea la resistencia a patógenos, insectos, moluscos y permite dar a los cultivos una resistencia a hongos Además, tiene propiedades antibióticas que favorecen la lignificación de los tejidos, la disminución de la calidad nutricional, la palatabilidad y la digestibilidad, todo lo que genera un decremento en la preferencia de los insectos por las plantas.…”

“…In this study, compared to CFs, the effect of CM–CFs on AH‐N was obscured by (NH 4 ) 2 SO 4 during 0–180 day, but during 180–360 day, when CM–CFs significantly increased AH‐N, and was mainly dependent on initial CM application rate, which was similar to the result reported by Tao et al . (). This may be attributed to CM improving soil biological activity and increasing the source of AH‐N from the CM.…”

We investigated the effects of compost (CM), made from poultry and cattle manure with spent mushroom substrate, plus chemical fertilizers (CFs) on soil organic carbon (C) and nitrogen (N) fractions in silty loam soil of the Loess Plateau. Eight fertilizer practices were applied in a 7‐year‐old ‘Red Fuji’ apple (Malus domestica Borkh.) orchard for 360 days. Compared to CM alone, CM–CFs decreased slightly soil total organic C but increased total N by 4.3–11.6%. Notably, CM–CFs increased soil microbial biomass C (MBC) by 2.7–26.5% and microbial biomass N (MBN) by 7–13.7%. Soil water‐soluble carbon (WSC) was increased by 20.7% and 19.2% when 2% CM plus N and phosphorus (P) (2%M–NP) and 4% CM plus N and P (4%M–NP) were applied, respectively. Whereas 0.5% CM plus N and P (0.5%M–NP) increased WSC by 9.3% on day 30 but decreased it by 7.2% from 30–360 days. Hot water‐soluble C increased by 13.1–14.6% from 0–180 day, but thereafter, the effect disappeared. Compared to CFs, CM–CFs increased MBN by 35.1–115.6%, and increased alkali‐hydrolyzable‐N by 3.5–55.8% over 180–360 days of incubation. Additionally, CM–CFs promoted N mineralization, increasing NH4‐N and NO3‐N contents. Based on the changes in C and N fractions and available nutrients, 2%M–NP (45 t/ha of CM plus 450 kg/ha of N and 157.5 kg/ha of P) may be the optimal fertilizer strategy for stimulating soil microbial growth and activity, and enhancing nutrient cycling for apple growth.

“…Furthermore, the organic matter content was 21 times higher in the SS treatment compared with the one in the ES. It is known that higher content of organic matter provide higher amounts of macronutrients and also a higher bioavailability of these nutrients [40,41]. Moreover, the addition of municipal SS resulting from the waste water treatment facilities contributes to the enrichment of microbes in soil that produce enzymes (dehydrogenases, phosphatases, peroxidases, etc.)…”

Currently, wastewater treatment plants produce large amounts of sewage sludge. Due to the rich content of organic matter and minerals, sewage sludge can be used as soil amendments for eroded soils. The aim of this work was to assess sewage sludge (SS) in combination with an eroded soil (ES) collected from the North Eastern Romania as growth substrate for sweet basil, and their effect on basil growth and physiology. The experiment was conducted in a greenhouse under controlled environment conditions. The tested substrates were: (1) eroded soil, ES; (2) mixture of eroded soil (15%) + sewage sludge, ES + SS (85%); and (3) sewage sludge, SS (100%). Three types of parameters were studied: morphological traits, physiological, and biochemical parameters. The maximum quantum yield of Photosystem II Fv/Fm was reduced in basil leaves grown on eroded soil (0.80) and was close to the normal value in ES + SS (0.83). Chlorophyll a and the carotenoids content were higher for plants grown on SS and significantly higher for those grown in ES + SS compared with the one of plants grown on ES. The fresh biomass yield and height of basil increased with 44% and 34.5% under ES + SS over ES. Total phenolic content was higher in plants grown on ES (7.34 mg/g dry weight Gallic acid equivalent), which also led to an increased antioxidant activity (44.4%) evaluated by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Fourier-Transform Infrared (FT-IR) (4000-400 cm −1 ) spectra of basil did not show significant qualitative differences among the plants from different treatments. The results of this study demonstrated that SS application led to the improvement of the basil morpho-physiological parameters, allowing the growth of basil on ES + SS.
