Phosphorus (P) is one of the primary nutrients limiting crop production. The application of phosphate fertilizers in acidic soils leads to the formation of secondary insoluble compounds that reduces the effectiveness of the fertilizer. The addition of biochar may represent a solution to the problem of nutrients bioavailability, especially P. In this study, tests were performed to determine the effects of amending soil with five different percentages of biochar (0, 5, 10, 20, and 35% w/w) on the phenomena of P sorption and desorption. The effect of soil/ biochar contact treatments on P availability was also examined. Phosphorus sorption was lower in the soils containing biochar compared to normal soil. The accumulated desorption quantity after eight consecutive extractions was 85% higher when 35% biochar was added to the soil than soil alone. Moreover, the application of 35% biochar increased the concentration of soluble P up to 38% after 30 days of incubation. Based on these results, we deduced that biochar induces changes in P retention soil properties that may be beneficial for agricultural soils.

Sustainable soil fertility management requires amendments that improve nutrient retention while supporting nutrient recycling. This review synthesizes current evidence on how biomass type and pyrolysis conditions determine biochar properties and, consequently, the dynamics of N, P, K, S, Ca, and Mg in soils. The analysis integrates bibliometric screening, comparative data on feedstock groups, and mechanistic evidence on adsorption–desorption, ion exchange, precipitation, microbial transformations, aging, and nutrient release. Feedstocks were grouped into agricultural, woody, animal, urban, and aquatic biomasses, whose mineral composition and structural features produced contrasting nutrient-source potentials. Across the biochars reviewed, pyrolysis temperatures ranged from 200 to 900 °C, generating materials with pH values of 4.7–13.7, surface areas of 0.18–545.66 m2 g−1, and nutrient contents of 0.04–8.22% N, 0.02–5.30% P, and 0.15–7.01% K. Higher pyrolysis temperatures generally increased aromaticity, alkalinity, porosity, and mineral concentration, whereas mineral-rich feedstocks provided greater direct nutrient and base-cation inputs. This review shows that BC functionality is context-dependent and should be matched to soil nutrient limitations, pH, texture, and crop requirements to improve nutrient-use efficiency and support sustainable agriculture.

Thermochemical treatments such as pyrolysis and hydrothermal carbonization (HTC) are increasingly used to convert municipal sewage sludge into solid products, offering benefits in contaminant reduction, pathogen sanitization, and nutrient recovery. This study assesses the agronomic potential of pyrochars and hydrochars produced under varying temperatures and residence times. Pyrolysis was performed at 250–520 °C for 20 and 60 min, while HTC was conducted at 180–300 °C for 30–120 min. Proximate and ultimate analyses revealed that pyrochars exhibit higher thermal stability and fixed carbon content, whereas hydrochars contain less condensed aromatic structures, indicating greater chemical reactivity but lower long-term stability. Surface area measurements showed meso- and macropore development in both materials, with hydrochars ranging from 14.7 to 86.0 m2·g−1 and pyrochars from 12.7 to 41.7 m2·g−1. Pyrochars tend to have a near-neutral pH, while hydrochars are slightly acidic. Hydrochars also retain higher levels of available nutrients (N, P, and S), particularly at lower temperatures, making them promising for agricultural applications. Agronomic evaluation confirmed greater N-NH4+ and phosphorus availability in hydrochars compared to pyrochars, suggesting their potential as soil amendments or fertilizer additives. However, the mobility of heavy metals requires further assessment to ensure environmental safety.

Aunque en la actualidad existe una gran preocupación por la contaminación y los posibles efectos sobre la salud que genera el uso frecuente de herbicidas, los estudios ambientales en los países tropicales son escasos, especialmente en Colombia. Por tanto, en el presente trabajo se evaluó la adsorción-desorción de diurón y ametrina en un suelo de Colombia (SC) y de España (SE). Los ensayos de adsorción-desorción se realizaron con moléculas de los herbicidas marcados con 14C, empleando la técnica batch equilibrium. En ambos suelos y para ambos herbicidas hubo un buen ajuste a las isotermas de Freundlich con R2 mayores a 0,99. Para diurón, en SE (Kfa = 12,82 ± 1,23) hubo mayor poder de adsorción frente a SC (4,56 ± 0,26). Por el contrario, para la ametrina se encontró un valor de Kfa = 6,47 ± 0,25 en SC y de 3,05 ± 0,08 en SE, mostrando mayor interacción con SC en comparación con SE. Para diurón se observó un grado de histéresis mayor en SC y para ametrina en SE, mostrando que la interacción de los dos herbicidas con los componentes de cada suelo es diferente dependiendo de su constitución mineralógica y su valor de pH.
