Wood ash effects on growth and cadmium uptake in Deschampsia flexuosa (Wavy hair-grass)

Growth and development of cowpea under wood ash doses and liming

“…This pattern of increase in biomass may be due to wood ash containing essential macronutrients, such as K and P (CRUZ-PAREDES et al, 2017) and N mineralization in soil due to wood ash (VESTERGÅRD et al, 2018). The results obtained in this study corroborate those found by Kindtler et al, (2019) that observed an increase in soil pH whose values increased from 3.83 to 8.00 by the application of 30 t ha -1 of eucalyptus wood ash. For Bonfim-Silva et al, (2015) this increase of pH in the soil can be attributed to the release of potassium carbonate by the reaction of the wood ash in the soil.…”

“…The soil pH increased from 1.49 in the soil control to 6.99 in the highest wood ash dose, thus demonstrating the potential of the wood ash in neutralizing the soil acidity, without the correction with limestone, confirming that the wood ash was efficient as soil concealer. The increase in soil pH due to wood ash occurred at the appropriate interval for most crops KINDTLER et al, 2019).…”

“…Wood ash is an alternative for use as corrective and fertilizer (JOHANSEN et al, 2019). Provides increased nutrients (HUOTARI et al, 2015;LEWANDOWSKI, 2016), water retention capacity (BÄR et al, 2018;THOMAZ, 2018), soil pH (CRUZ-PAREDES et al, 2017;FÜZESI;HEIL;KOVÁCS, 2015) and enhances nitrogen fertilization (BRAIS; BÉLANGER; GUILLEMETTE, 2015) contributing to optimizing crop productivity (CRUZ-PAREDES et al, 2017;KINDTLER et al, 2019).…”

Mudança No Uso E Ocupação Do Solo Na Bacia Hidrográfica Do Rio Uruçuí-Preto, Piauí.

“…Arshad et al (2019) avaliando os efeitos dos níveis de cinza vegetal no crescimento de mudas de feijão-caupi, concluíram que o feijão-caupi tem um alto potencial de cultivo na presença de cinzas vegetal com uma concentração de pelo menos 20 %, o que valida os resultados encontrados neste trabalho em relação ao potencial uso de cinzas vegetal para esta cultura. KINDTLER et al, 2019).…”

“…A cinza vegetal é uma alternativa para a utilização como corretivo e fertilizante (JOHANSEN et al, 2019). Proporciona o aumento dos nutrientes (HUOTARI et al, 2015;LEWANDOWSKI, 2016), da capacidade de retenção da água (BÄR et al, 2018;THOMAZ, 2018), do pH do solo (CRUZ-PAREDES et al, 2017;FÜZESI;HEIL;KOVÁCS, 2015) e potencializa a adubação nitrogenada (BRAIS; BÉLANGER; GUILLEMETTE, 2015) contribuindo para otimização da produtividade da cultura (CRUZ-PAREDES et al, 2017;KINDTLER et al, 2019). BÄR et al, 2018;PEREIRA et al, 2016).…”
