Dairy wintering systems in southern New Zealand : quantification and modelling of nutrient transfers and losses from contrasting wintering systems : a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Soil Science at Massey University, Palmerston North, New Zealand [PDF]
Traditional dairy wintering practice in the lower South Island of New Zealand has been to graze brassica crops in situ. This practice has been under increasing scrutiny from local Regional Councils due to the relatively high nitrogen (N) leaching ...

Water percolation estimated with time domain reflectometry (TDR) in drainage lysimeters
Due to the difficulty of estimating water percolation in unsaturated soils, the purpose of this study was to estimate water percolation based on time-domain reflectometry (TDR).

Effect of the Presence of Nonionic Surfactant Brij35 on the Mobility of Metribuzin in Soil
Given the water scarcity becoming endemic to a large portion of the globe, arid region irrigation has resorted to the use of treated, partially treated, or even untreated wastewaters.

No3-N and metolachlor concentrations in the soil water as affected by water table depth [PDF]
Experiments were conducted in lysimeters to study the effect of shallow water table (WT) depths on the transport of two commonly used agricultural chemicals, nitrate-N and metolachlor, to shallow groundwater. Groundwater samples were collected from 0.20-,

A simple lysimeter soil retriever for mini lysimeters.
Abstract A lysimeter-soil retriever (LSR) is a device used to retrieve the soil with minimum disturbance from lysimeters. This device makes the process of sampling intact soil layers from lysimeters easier and faster especially when a large number of lysimeters are being sampled. In this study, mini lysimeters (200 mm diameter and 25 kg weight)

Water Requirements and Irrigation Scheduling for HLB-affected Citrus Trees
There is an urgent need for strategies to sustain production of citrus trees affected by HLB without depletion to our water resources. Understanding the role of evapotranspiration (ET) in Huanglongbing (HLB) affected trees is critical for determining if ...
