4 Benefits of Using Power-Z Sustainable Soil Additive for Agriculture Companies
There are many complex aspects to soil quality that can affect the growth and health of plants. Soils in different areas have different physical and chemical compositions that can be good or bad for farming. In the case of naturally rich and beneficial soil, over time, nutrients will be depleted. For other soils, plants could not be grown well there naturally. In those cases, a sustainable soil ...

Persistence and management of dinitroaniline herbicides residues in sandy loam soil
The addition of organic manure affects the biological, chemical and physical properties of soil that control the fate of herbicides. Three dinitroaniline herbicides were studied to asses their persistence, dissipation and residue management in sandy loam soil with and without addition of farmyard manure (FYM) under middle western Indian agro-climatic conditions. The herbicides, pendimethalin ...

A statistical approach to evaluate compost genotoxicity
Parallel experiments were carried out to evaluate the induction of genotoxic effects in Vicia faba seedlings treated both with aqueous and organic extracts (dimethyl sulphoxide 5%) of 13 composts, or grown on soil samples to which different doses of the same composts were added. Pearsons linear correlation coefficient and multiple regression were used to study how these two different ...

Phytotoxic effects of Cu and Zn on soybeans grown in field-aged soils: their additive and interactive actions
Received for publication June 16, 2006. A field pot experiment was conducted to investigate the interactive phytotoxicity of soil Cu and Zn on soybean plants [Glycine max (L.) Merr.]. Two soils (Arkport sandy loam [coarse-loamy, mixed, active, mesic Lamellic Hapludalf] and Hudson silty clay loam [fine, illitic, mesic Glossaquic Hapludalf]) spiked with Cu, Zn, and combinations of both to reach the ...

Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)
The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

Adsorption of glyphosate on variable-charge, volcanic ash–derived soils
Glyphosate (N-phosphonometylglycine) is widely used due to its broad spectrum of activity and nonselective mode of action. In Chile it is the most used herbicide, but its adsorption behavior in the abundant and widespread variable charge soils is not well understood. In this study, three volcanic ash–derived soils were selected, including Andisols (Nueva Braunau and Diguillin) and Ultisols ...

Effect of charcoal quantity on microbial biomass and activity in temperate soils
Wildfire-produced charcoal is a common component of soils, affecting a range of important abiotic and biotic soil processes. Our ability to predict the effects of charcoal addition to soil is currently limited, however, by our understanding of how charcoal affects the soil microbial community mediating many of these processes. This study sought to improve our understanding of the relationship ...

Soil genotoxicity induced by successive applications of chlorothalonil under greenhouse conditions
Greenhouse production of vegetables has been developed rapidly in China. High temperature and humidity inside the greenhouse make this environment more suitable for fast reproduction of fungal diseases. Fungicides are among intensively used chemicals in the greenhouse to prevent crops from the invasive infection of phytopathogen, however, little is known about accumulation of fungicides in ...

Evaluation of three models that describe soil water retention curves from saturation to oven dryness
Measuring a soil water retention curve (SWRC) with the pressure plate device is generally limited to matric suctions 1500 kPa. A few models have been proposed to describe the SWRC from saturation to oven dryness using measurements in the pressure plate matric suction range. The development and validation of these models were mostly based on a limited set of published measurements, and in general, ...

Application of two vermicomposts on a Rice crop: Effects on soil biological properties and rice quality and yield
Vermicomposts have been considered as a soil additive to reduce the use of mineral fertilizers because they provide required nutrients, increase cation exchange capacity, and improve water-holding capacity. However, the effect of each vermicompost on soil properties and crop yield depends on its chemical composition. The main objective of this work was to study the effect of incorporating two ...

Effectiveness of recovered Magnesium Phosphates as fertilizers in neutral and slightly Alkaline soils
Magnesium phosphates such as struvite (MgNH4PO4 · 6H2O) can be recovered from municipal, industrial, and agricultural wastewaters. However, limited information is available on the beneficial reuse of these recovered products; research has focused on low pH soils. This study determined whether recovered struvite and dittmarite (MgNH4PO4 · H2O) were effective P fertilizers in neutral to slightly ...

Uncomposted wool and hair-wastes as soil amendments for high-value crops
The hypothesis of this work was that uncomposted sheep wool and human hair could be used as nutrient source for nonedible high-value plants. Pot and field experiments were conducted to assess uncomposted sheep wool-wastes and human hair-wastes as a nutrient source for high-value crops and to evaluate the effect of these waste materials on soil microbial community and mycorrhizae. In the pot ...

Soil CO2 Flux Measurements -- Atmospheric CO2 Profile Measurements Using the LI-8100/8150 System
The LI-8100 Automated Soil CO2 Flux System has been designed to help answer the spatial and/or temporal variability questions that arise when performing soil CO2 flux measurements. When using the LI-8150 Multiplexer with the LI-8100 Analyzer Control Unit, atmospheric CO2 profile measurements can be performed in addition to soil CO2 flux measurements, with minimal added cost. This application note ...

High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska
Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

Effect of AgraGel T-400 on tomato crops, U. of Valparaiso, Chile - Case Study
Introduction At present, a great part of vegetable production in Chile is dedicated to industrial agronomy and one of the most important products is the tomato crop for industrial processing. Chile has a capacity of 180,000 tons of tomatoes per year, which is equivalent to 12,000 hectares of crop land. Among canned products tomato paste represents 38%. This is an important employment generating ...

This Spring, Make your Seed Work Harder for you
Just like other investments I make, I want my seed to work as hard as possible for me to see the return in the fall. Of course, the decisions I make between now and then influence how good of a harvest season I’ll have. Over the years, using variable rate seed prescriptions has helped ensure I’ve got the right amount of seed in the right areas of the field to make a return. Now, ...

The role of natural purified humic acids in modifying Mercury accessibility in water and soil
Received for publication April 17, 2008. Contamination of soils with mercury can be a serious problem. It can be mobilized or stabilized by humic substances (HS) containing binding sites with reduced sulfur that can have different binding capacities for CH3Hg+ and for Hg2+. In this work we investigated the influence of different humic acids (HAs, extracted from lignite, compost, and forest soil) ...

Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...
