1. Effects of organic liquid fertilizers on biological activities and fruit productivity in open-field cherry tomato
ABSTRACT This study evaluated the effects of liquid fertilizers (LF) with farm-derived renewable resources on biological activities and chemical attributes of the soil and fruit in an open-field tomato (Lycopersicon esculentum var. cerasiforme) experiment conducted in South Korea in the 2019 growing season. The LF treatments included bone+fish meal (BF), fis

2. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

3. Phosphate Sources and Filter Cake Amendment Affecting Sugarcane Yield and Soil Phosphorus Fractions
ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and tri

4. Lime and calcium-magnesium silicate in the ionic speciation of an Oxisol
ABSTRACT Plant residues and certain fertilizers accelerate soil acidification and increase the levels of aluminum-Al+3 in soils under no-tillage (NT). Silicates act as acidity amendments and as a source of silicon as in H4SiO4. An increase in the pH of soil solution causes the deprotonation of H4SiO4 and generates the anionic form (H3SiO4−). The aim of thi

6. Biomassa carbonizada como condiciondor de solo: aspectos agronômicos e ambientais do seu uso em solos de cerrado / Biochar as soil amendment: agronomic and environmental aspects of its application in soils of the Brazilian savana (cerrado)
Estudou-se o efeito do carbono pirogênico nas características químicas e biológicas do solo, na fisiologia e produtividade das culturas da soja e do arroz de terras altas e na emissão de N2O para a atmosfera. Os experimentos foram realizados em Nova Xavantina, MT, em dois diferentes tipos solos: Latossolo Vermelho Amarelo (soja) e Cambissolo Háplico (a

7. Study of potential impacts of using sewage sludge in the amendment of desert reclaimed soil on wheat and jews mallow plants
This investigation was conducted to study the impacts of using sewage sludge at different concentrations (0, 10, 25, 50, 75%) in amendment of desert reclaimed soil properties and some physiological aspects in wheat and jews mallow plants. Generally adding sewage sludge to desert soil improved the soil texture, raised the organic matter contents, water holdin

8. Coffee seedlings (Coffea arabica L.) grown in a commercial substrate amended with organic material sources / Mudas de cafeeiro (Coffea arábica L.) desenvolvidas sob fontes de material orgânico no substrato comercial
O objetivo deste trabalho foi avaliar o desenvolvimento de mudas de cafeeiro (Coffea arabica L.) sob cinco proporções (0, 15, 30, 45 e 60% com base em volume) de três fontes de material orgânico (esterco bovino, cama de frango e húmus de mata) adicionadas ao substrato comercial Bioplant Café. O delineamento foi em blocos ao acaso, com quatro repetiçõ

10. Remediation of cadmium- and lead-contaminated soils with an aluminum industry by-product / Subproduto da indÃstria de alumÃnio na remediaÃÃo de Ãreas contaminadas com cÃdmio e chumbo
Mining activities have been increasing each day and generate large amounts of residues or by-products, which have caused a lot of interest by researchers in evaluating their potential use as soil amendments. One of the applications of such amendments is on the remediation of soils contaminated with trace elements, which might pose a threat to animals and pla

12. Biodegradation, sorption and desorption of 14C-diuron in two brazilian soils amended with sewage sludg. / Biodegradação, sorção e dessorção do herbicida 14C-Diuron em dois Latossolos tratados com lodo de esgoto.
Adding sludge to agricultural soil may modify the behavior of pesticides in the soil. In some cases, the application of organic amendment increases the degradation of pesticides, by providing nutrients and energy to the microorganisms able to degrade the molecule (Felsot &Dzantor, 1990), in other cases, the sorption is increased, resulting in the decrease of
