Total P

The phosphate (P) present in a range of parent rocks for hill country soils in Wairarapa region, New Zealand, has been studied. In general the highest P concentrations occur in the mudstones which contain 50% more P than the fine to medium sandstones, and at least 10 times more P than the coarse sandstones. Most of the P is in the 20-2 �m and <2 �m size fractions of the rocks. The P is present both in apatite and calcite mineral grains. Although the highest P concentrations occur in the heavy fraction (containing apatite), most of the total P is held in the light fraction in which calcite is abundant and where some apatite also occurs within aggregates. Since both calcite and apatite are relatively soluble in this soil environment, and since both have large reactive surfaces, they may readily release P for plant growth.

Tall fescue (Festuca arundinacea) is a useful alternative to ryegrass in New Zealand pasture but it is slow to establish. Naturally occurring beneficial bacteria in the rhizosphere can improve plant growth and health through a variety of direct and indirect mechanisms.

The Hill

This paper provides a stocktake of the status of hill country farming in New Zealand and addresses the challenges which will determine its future state and performance. It arises out of the Hill Country Symposium, held in Rotorua, New Zealand, 12-13 April 2016. This paper surveys people, policy, business and change, farming systems for hill country, soil nutrients and the environment, plants for hill country, animals, animal feeding and productivity, and strategies for achieving sustainable outcomes in the hill country. This paper concludes by identifying approaches to: support current and future hill country farmers and service providers, to effectively and efficiently deal with change; link hill farming businesses to effective value chains and new markets to achieve sufficient and stable profitability; reward farmers for the careful management of natural resources on their farm; ensure that new technologies which improve the efficient use of input resources are developed; and strategies to achieve vibrant rural communities which strengthen hill country farming businesses and their service providers.

Metabolic energy budgeting (MEB) was used to evaluate evolution over 30 years (1980–1981 to 2010–2011) in New Zealand southern North Island ‘hill country’ sheep and beef cattle systems. MEB calculates energy required by animals for body weight maintenance, weight gain or loss, pregnancy, and lactation to estimate the system feed demand and thereby provide a basis for calculating feed conversion efficiency. Historic production systems were reconstructed and modeled using averaged data from industry surveys and data from owners’ diaries of three case-study farms and reviewed for patterns of change over time. The modeling indicated that pasture productivity was 11% lower and herbage harvested was 14% lower in 2010–2011 than in the early 1980s. This productivity decline is attributable to warmer, drier summer weather in recent years. However, primarily through increased lambing percentage, feed conversion efficiency based on industry data improved over the study period from 25 to 19 kg feed consumed per kg lamb weaned, while meat production rose from 137 to 147 kg per ha per year. Similar improvements were observed for the three case farms. The New Zealand MEB model was found effective for analysis of tropical beef production systems in Sabah, Malaysia.

Abstract:Pannaria leproloma is shown to be a New Zealand endemic, and is characterized by coarse isidiomorphs/isidia, a high frequency of apothecia and the presence of two cytotoxic scabrosin esters, previously unknown from Pannariaceae, and present in 40 of the samples studied. It is not a member of the Pannaria sphinctrina group, as previously thought. It has frequently been confused with a related, finely sorediate, very sparingly fertile species, which lacks scabrosin esters in more than 99 of the specimens studied. This latter species is widely distributed both in southern South America (where it is one of the most common corticolous lichens), south-eastern areas of Australia and in New Zealand. It was originally described as Psoroma isidiosum, but had to be renamed when transferred to Pannaria, and is here named Pannaria farinosa.

Sown Area

Of the 5 1/4 million acres of total occupied land in the Wellington district nearly 4 million acres are in sown pasture, the remainder being bush, natural tussock grassland, scrub and secondary growth. Of this sown area a large proportion comprises hill-country farms running sheep and beef cattle and carrying an average of 1 to 2 sheep per acre. From the sheepfarming point of view the Wellington district is of major national importance, contributing nearly 22 per cent. of the total sheep population and almost 19 per cent. of the total beef cattle. The region as a whole carries the heaviest concentration of stock of all New Zealand.

Growth Promoting

The modern agricultural sector is mainly dependent on synthetic fertilizer for enhancing the growth of crop improvements but a burden of inorganic and chemical-based fertilizer currently created a serious threat to human health as well as the soil environment. Fertilizer research is therefore focusing on an alternative to chemical fertilizer by exploiting natural sources such as marine macroalgae or seaweed. The use of seaweed will be an eco-friendlier approach to sustainable agriculture. Marine macroalgae or seaweed widely applicable in plant growth enhancements due to the presence of biological active phycocompounds such as proteins, phenolic compounds, amino acids, polysaccharides, plant-growth-promoting hormones, and some growth factors, etc. Several research studies have been carried out on the applicability of seaweed or the effect of marine algae or its components on plants and its quality. These types of constituents play their role in improving the morphological as well as biochemical characteristics of plants. The present review study focuses on the applicability of marine macroalgae as a biofertilizer or plant growth stimulator in agricultural applications. This study further helps to improve the nutritional quality of crops which prove to be useful in further investigations and applications.

Thank you for the opportunity to present this address in my home district, from where I started my business career in aviation in 1949. The 34 years have been eventful, stimulating and satisfying, particularly when it has been said so many times that the agricultural aviation industry has been the single most important development in post war years, in arresting the lost production from New Zealand hill country. The main contribution tq,the threefold increase in stock unit numbers has been the service provided by the aviation industry. It is a record that we, who created it, and spent our working lifetime on, can be justly proud.

Distribution And Ecology

AUSTRALIAN SEDGE (Carex longebrachiata) is potentially a serious weed on North Island hill country which lacks a vigorous sward. Its recognition as a weed, acknowledged by its inclusion in the Noxious Weeds Act in 1962, was delayed until some infestations were completely out of control. This account summarizes existing information on this plant with particular reference to the northern part of New Zealand.
