The in ̄uence of row position and selected soil attributes on Acarina and Collembola in no-till and conventional continuous corn on a clay loam soil
Population abundances of both Acarina (mites) and Collembola (springtails) were examined for continuous corn grown under no-till and conventional management practices on a clay loam, an Orthic Humic Gleysol (Typic Haplaquoll) near Ottawa, Ont., Canada (Lat. 458 220 N; Long. 758 430 W). For each tillage practice, samples for soil faunal extraction and soil attribute characterization were taken p...
متن کاملDevelopment and Evaluation of a Real Time Site-Specific Inter-Row Weed Management System
ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...
متن کاملChemical attributes of soil under no-till farming affected by crop systems and fertilization sources
Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; 0.10-0.20; and 0.20-0.40 m in depth were collected and analyzed in the second year of an experiment installed in 2006 in a Rhodic Hapludox under no-till farming, located in ...
متن کاملSize and Activity of the Soil Microbial Biomass in the Row and Inter-row of a Sugarcane Field under Burning and Green Cane Harvesting
The size and activity of the soil microbial biomass was studied in the plant row and in the inter-row of a sugarcane field under burning or green cane harvesting. The sites sampled were on the long-term trash management trial situated at Mount Edgecombe. Soils were sampled to 30 cm depth in (i) the centre of the plant row, (ii) 30 cm out from the row centre and (iii) 60 cm out from the row cent...
متن کاملPrevious Corn Row Effects on Potassium Nutrition and Yield of Subsequent No-Till Soybeans
Narrow-row soybean [Glycine max (L.) Merr.] production in corn [Zea mays L.]–soybean rotations results in various distances of soybean rows from previous corn rows, yet little is known about soybean responses to proximity to prior corn rows in no-till systems. The objective of this study was to evaluate the impacts of preceding corn rows on potassium (K) nutrition and yield of subsequent no-til...
