Effect of surface application of urea, ammonium-sulfate and lime on exchangeable cation distribution in an inceptisol in humid tropical Queensland

Autor: GP Gillman, KL Bristow

Publikováno v: Soil Research. 28:39

The effect of two sources of N (urea and ammonium sulfate) on the leaching of exchangeable cations in an Inceptisol was examined in the field over a 6 week period. During this time, artificial rainfall (60, 80 and 90 mm) was applied on three occasion

Phosphate sorption characteristics of soils of the north Queensland coastal region

Autor: FG Thomas, BN Toreu, GP Gillman

Publikováno v: Soil Research. 26:465

Phosphate-sorption curves covering the range of supernatant P concentration, 0-1 �g nil-1, have been determined for a number of agriculturally important soils in the high rainfall (2000-4000 mm) region of tropical Queensland. Where possible, soil s

Leaching of applied calcium and potassium from an oxisol in humid tropical Queensland

Autor: KL Bristow, MJ Hallman, GP Gillman

Publikováno v: Soil Research. 27:183

Downward movement of Ca and K applied to a north Queensland Oxisol has been studied in the field where rainfall is approximately 4000 mm per annum. After cultivating the soil to about 15 cm depth, Ca was applied as lime (5 tha-1) and gypsum (8.6 t ha

The grouping of soils with similar charge properties as a basis for agrotechnology transfer

Autor: DF Sinclair, GP Gillman

Publikováno v: Soil Research. 25:275

A set of 94 variable charge soils (Oxisols and Ultisols) from humid tropical Queensland has been formed into three groups on the basis of their surface charge characteristics. Mean curves of basic cation exchange capacity (CECB) against pH, total cat

Effects of sample handling on some chemical properties of soils from high rainfall coastal north Queensland

Autor: GP Gillman, GG Murtha

Publikováno v: Soil Research. 21:67

The effects of drying, storing in an air-dry condition, and collecting samples at different times of the year, on cation exchange properties and phosphate sorption characteristics have been examined for two soils from coastal north Queensland. The pr

Plant nutrition studies on some yellow and red earth soils in northern Cape York Peninsula. 1. Soils and their nutrient status

Autor: RF Isbell, GP Gillman, RK Jones

Publikováno v: Australian Journal of Experimental Agriculture. 16:532

Eleven complete profiles and an additional 112 surface soils of deep sandy yellow and red earths in the far northern part of Cape York Peninsula have been sampled for laboratory studies. Chemical analyses showed that these acid soils are very low in

Studies on some deep sandy soils in Cape York Peninsula, North Queensland. 3. Losses of applied phosphorus and sulphur

Autor: GP Gillman

Publikováno v: Australian Journal of Experimental Agriculture. 13:418

Losses of applied phosphorus and sulphur from a 100 cm profile of a deep siliceous sandy soil in Cape York Peninsula have been studied in the field over a period of three wet seasons. The P and S was applied in two treatments: superphosphate (880 kg

Studies on some deep sandy soils in Cape York Peninsula, North Queensland. 1. Morphological and chemical characteristics

Autor: GP Gillman, RF Isbell

Publikováno v: Australian Journal of Experimental Agriculture. 13:81

Deep sandy soils overlying granitic rocks are widespread in Cape York Peninsula. Rainfall is summer dominant and the annual mean is 1140 mm. Evidence is presented that some of the soils are weakly podzolised and some soil properties are influenced by
