ABSTRACT Irrigating turfgrass with treated effluent water has become a common practice in response to shrinking supplies of potable water. Newly developed decentralized treatment systems produce recycled containing varying quantities N on short notice. Using such tailored irrigate turf areas would reduce or eliminate the need for additional mineral fertilizers if concentrations nitrate were raised during growing season meet annual requirement. On basis our estimates, order turfgrasses...

Abstract The widespread use of warm‐season turfgrasses in transition zones Europe, such as northern Italy, has been hampered by the long dormancy periods. To encourage conversion from cool‐ to grasses, research is needed identify cultivars that exhibit early spring green‐up. A 2‐year study was conducted at agricultural experimental farm Padova University November 2006 October 2008 compare water‐soluble carbohydrate and protein content stolons four bermudagrass [ Cynodon dactylon (L.)

Core Ideas Soil carbonate is typically viewed as a soil mineral that requires centuries to accumulate; our study indicates it can be generated in months years. If the source of Ca directly from silicate minerals, could managed sequester atmospheric CO 2 . Carbon‐13 values change less than decade for both organic and inorganic C. This uses an experimental pedology approach using controls, treatments, replications. examine (i) how conversion native C 4 grassland 3 woody shrubs then irrigated...

Abstract Bans on the use of synthetic herbicides require innovative management approaches to maintain attractiveness and usability turfgrass swards. Such measures should include locally adapted cultivars that germinate establish quickly, resulting in densest possible stands. Additionally, a number turfgrasses have been reported produce allelopathic substances inhibit common weeds. Mowing heights be set achieve maximum weed suppression while still providing acceptable quality for desired use....
