Recently in the Goondiwindi area in the Macintyre Valley, cotton roots depths were tested in various cotton fields using a capacitance probe. It was found some crops were drawing water from 100cm, some 80cm and about 30% were only around 60cm deep late in the season. The shallower roots depths could be caused from poor
Pacific Fertiliser releases a new Ag lime product for the Central & South West Regions in NSW. The high analysis lime product specifically made for agricultural use. The sub 1mm sizing allows for better handling, increased spreading accuracy and minimal dust loss during application, without effecting solubility. The general specifications of Pacific Fertiliser's Ag Lime: -
Putting the dollars into sodic soil management Key Points of the GRDC article: - Sodicity is the presence of too much sodium (Na) in the soil. - Australia represents the majority of the world’s sodicity issues which can lead to a reduction in plant growth and grain yield as well as decreased soil structural ability.
Long-Term mineral Key to Soil Microbial Biomass Conclusions from a review of extensive international research are not surprising but extremely significant. Soil organic carbon increased by 13 per cent and microbial biomass increased by 15% in the average of 64 long-term international research studies using mineral nitrogen fertiliser applied to annual crops, when compared with
Sulfur (S) deficiencies have been recorded in cereal crops of the Darling Downs, since the early 1980s and symptoms are commonly mistaken as N deficiency. Few experiments have been successful in measuring soil parameters indicative of S responsive soils. A grain yield response in sorghum was recorded in a long-term S experiment during the 1998-99
Animal manure when applied to cropland, can supply nitrogen and other nutrients necessary for plant growth. Asutralia's soils are generally naturally low in organic matter. The use of animal manure on cropland can increase the tilth, aeration, water-and nutrient-holding capacities, infiltration rate, organic matter content, and microbial activity of soil. Manures from concentrated animal feeding operations
Here are five key benefits of gypsum application: 1. Source of calcium and sulfur for plant nutrition. Plants are becoming more deficient for sulfur and mot soil are not supplying it. Gypsum is an excellent and cheap source of sulfur for plant nutrition and improving crop yield. 2. Improves soil structure. Flocculation, or aggregation, is
Pacific Fertiliser is trialing blending its soft rock phosphate fines with humates to increase the effectiveness of the blended product and increase the solubility of the soft rock by upto 2.5 times.
Pacific Fertiliser recently undertook detailed research into the bulk agricultural gypsum products available on the eastern seaboard of Australia. This research continues on from the NSW Department of Primary Industries work in 1996 which was reported in the AgFact AC.10 (Agdex 514) document. The gypsum samples were obtained from various agricultural gypsum sources either ex
