Review of Maleic–Itaconic Acid Copolymer Purported as Urease Inhibitor and Phosphorus Enhancer in Soils
Autor: R. McBride, D C Edmeades, S. H. Chien, K. L. Sahrawat
Publikováno v: Agronomy Journal. 106:423-430
The fertilizer additive products Nutrisphere and Avail use a coating of maleic–itaconic acid copolymer and have been marketed worldwide. It is claimed that the copolymer (trade name: Nutrisphere) enhances the efficiency of urea-N use by inhibiting

The calcium requirements of pastures in New Zealand: A review
Autor: D. C. Edmeades, K. W. Perrott
Publikováno v: New Zealand Journal of Agricultural Research. 47:11-21
Calcium (Ca) plays a vital role in the structural integrity of soils, plants, and animals. This review considers the Ca status of New Zealand pastoral soils and examines the Ca requirements of pastures and animals. Against this background the diagnos

Sodium requirements for temperate pastures in New Zealand: A review
Autor: M. B. O'Connor, D. C. Edmeades
Publikováno v: New Zealand Journal of Agricultural Research. 46:37-47
Sodium (Na) is not an essential plant nutrient for forage pasture species but is required for optimal animal health and production. The distribution of Na in New Zealand pastures and soils is reviewed and evidence discussed indicating that the incide

The agronomic effectiveness of lime‐reverted and dicalcic superphosphates: A review
Autor: D. C. Edmeades
Publikováno v: New Zealand Journal of Agricultural Research. 43:1-6
Results from 10 field trials that compared the agronomic effectiveness of water‐soluble phosphate (WSP) fertilisers with reverted or dicalcic superphosphates (DCP) are reviewed. The 51 observed relative responses ranged from +20% to ‐10%, with a

Effect of lime on yield, N fixation, and plant N uptake from the soil by pasture on 3 contrasting trials in New Zealand
Autor: D. C. Edmeades, J. D. Morton, D. M. Wheeler
Publikováno v: New Zealand Journal of Agricultural Research. 40:397-408
The amount of plant nitrogen (N) uptake from the soil and fixed N in the herbage of clover species were measured using a 15N dilution technique on mowing trials at 3 lime rates (0, 5000, and 10 000 kg/ha) at a low rainfall site (Matapiro soil) near H

Effect of varying solution calcium or magnesium concentrations in the presence or absence of aluminum on yield and plant calcium or magnesium concentrations in wheat
Autor: D. C. Edmeades, D. M. Wheeler
Publikováno v: Journal of Plant Nutrition. 18:2229-2245
The effect of varying solution calcium (Ca) and magnesium (Mg) concentrations in the absence or presence of 10 μM aluminum (Al) was investigated in several experiments using a low ionic strength (2.7 × 10‐3 M) solution culture technique. Aluminiu
