Functional and community investigation of nodule endophytes for the selection of phosphate solubilizing rhizobial inoculants for clover : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
Nitrogen (N) and phosphorus (P) are limiting nutrients for plant growth and are the largest fertilizer inputs in agriculture. Phosphorus fertilizer has a low efficiency of use with only 5-30% utilized by the plant, the rest forming metal complexes and becoming unavailable to plants. In New Zealand, …

A study of some soil fertility problems in Canterbury
… was confined to the relatively productive plains and other readily accessible regions. That these areas have been highly developed agriculturally may be seen by the capability of some of them to give maximum pasture productions in recent years. Since productivity largely depends on soil fertility, …

The effect of the lime-molybdenum interaction on some properties of pasture soils
… element may mean the difference between low and high pasture production. It appears that molybdenum will continue to be used in this country for numerous trials have indicated that as far as pasture production is concerned, a few ounces of molybdenum give results as good as several tons of …

Copper deficiency in lucerne (Medicago sativa. L.)
… in some areas. The relationships between yield and plant composition were rather different from those predicted from other studies; it is considered that this indicated that the present understanding of these relationships is far from adequate. A survey of Cu content of Lucerne growing on Eyre, …

The profitability of nitrogen fertiliser usage on Canterbury irrigated sheep farms
… Effects of nitrogen usage on stocking rate and animal performance was determined. Current prices were used to determine profitability using partial budget analysis. Pasture nitrogen responses were thoroughly researched, and used as parameters in the model. Spring applied nitrogen with good …

Studies on the factors influencing inhibition of lateral buds and branches
The roles of light, nitrogen and I.A.A. in particular, have been investigated and evaluated in terms of their relative importance in the outgrowth of lateral buds. Both nitrogen and light are shown to be major factors in tillering of ryegrass and in addition that high nitrogen levels alone induce …

Evaluation of perennial ryegrass cultivars for dairy production under different pasture management
… cultivars for dairy production under different pasture management. Five experiments were conducted in Canterbury, New Zealand to evaluate perennial ryegrass in terms of morphology (experiment 1), nutritive value (experiments 1 and 2), rumen degradation (experiment 3), dietary preference …
