Fire Ignition

The interaction between grazing and fire influences ecosystems around the world. However, little is known about the influence of grazing on fire, in particular ignition and initial spread and how it varies by grazing management differences. We investigated effects of fall (autumn) grazing, spring grazing and not grazing on fuel characteristics, fire ignition and initial spread during the wildfire season (July and August) at five shrub steppe sites in Oregon, USA. Both grazing treatments decreased fine fuel biomass, cover and height, and increased fuel moisture, and thereby decreased ignition and initial spread compared with the ungrazed treatment. However, effects differed between fall and spring grazing. The probability of initial spread was 6-fold greater in the fall-grazed compared with the spring-grazed treatment in August. This suggests that spring grazing may have a greater effect on fires than fall grazing, likely because fall grazing does not influence the current year’s plant growth. Results of this study also highlight that the grazing–fire interaction will vary by grazing management. Grazing either the fall or spring before the wildfire season reduces the probability of fire propagation and, thus, grazing is a potential fuel management tool.

Limited Application

Yield and quality of forage mainly depend on the floristic composition, ie the share of higher quality grasses and legumes, soil fertility, amount and distribution of precipitation and light. Natural meadows and pastures are the most important resource in the forage production in the hilly and mountainous area of Republic of Serbia. Despite the large areas, the forage production on natural grasslands is relatively low. Limited application of a small number of agrotechnical measures is the main reason for low and unstable yields and poor forage quality. Only by appropriate fertilization of meadows and pastures with mineral and organic fertilizers, their rational exploitation, it is possible to achieve an increase in hay yield by several times and improvement in forage quality, simultaneously.

ABSTRACT: The aim of this study was to evaluate the performance and feed intake of grazing beef heifers on two grazing intervals determined by thermal sum related to leaf elongation duration during cool season on natural grasslands. A complete randomized block design experiment with two treatments and three replications was conducted from May to September 2011 in the central part of the state of Rio Grande do Sul, Brazil. The treatments were two thermal sums calculated at 375 and 750 degrees-days (DD) to determine the intervals between grazing periods in a rotational grazing system. Thirty six beef heifers with average age of 18 months old and (initial body weight = 220±14kg) were used, all heifers received ground corn supplement at a rate of 5g kg-1 of body weight per day, at 2p.m., throughout the experiment and had free access to mineral and protein supplementation (450g kg-1 of CP). Similar average daily gain (ADG), beef production gain (BPG) and feed intake (FI), were obtained in both treatments. Leaf elongation duration is an alternative grazing management tool for improved animal production and to increase animal stocking rate.

Abstract Integrated systems have been gaining prominence in recent years, especially the crop-livestock-forestry, which, in addition to being an alternative income per area, increase fertility and organic matter content in the soil, and protect animals against weather conditions. However, there is still a lack of knowledge about the management of pastures under such conditions. Therefore, the aim of this research was to evaluate the grazing management and nitrogen fertilization in Marandu palisade grass consorted with Eucalyptus to obtain the greater of forage production. The experimental design was a randomized block, arranged in split-plot, the plots were composed of two eucalyptus spacing (12 x 2 or 12 x 3) and Marandu monoculture, the subplots were composed of the nitrogen fertilization rate (0, 100, 200 kg N/ha using ammonium sulfate). The higher DM accumulation rate was observed at 200 kg N ha-1 (69.29 kg DM ha-1 day), while there was no difference between the treatments without fertilization and 100 kg N ha-1 (P &gt; 0.001). DM accumulation rate increased by 30.01% when fertilization increased from 100 kg N ha-1 to 200 kg N ha-1. Marandu palisade grass with 200 kg N ha-1 showed the highest production (28.82 t ha-1) independent of spacing. In the silvopastoral system, the greater accumulation of forage was observed when handled with 80% of the light interception (LI), corresponding to a height of 67 cm. Therefore, we conclude that Marandu grass in a silvopastoral system, without N fertilization, should be managed with a pre-grazing height of 60 cm and 73% LI. Marandu grass in a silvopastoral system, with 100 kg N ha-1 fertilization, should be managed with a height of 68 cm and 84% LI, and, with 200 kg N ha-1, should be managed at 80% of LI for the greater pasture utilization and development.

Stocking Rates

Five stocking rates, ranging from 0.8 to 2.8 beasts ha-1, and three frequencies of grazing were imposed on a five-year-old Siratro (Macroptilium atropurpureum)/Setaria anceps cv. Nandi pasture at Samford, south-east Queensland. The three grazing frequencies involved grazing for four days every three, six or nine weeks. Plots were individually grazed from 1972 to 1976 and the residual effect of treatments was measured over a grazing-free period in 1977. Within the three week grazing frequency both Siratro yield and total yield declined markedly with increased stocking rate, with an increased invasion of prostrate species such as blue couch (Digitaria didactyla). The decline in Siratro yield at higher stocking rates was less marked in the nine week system where there was much less invasion of prostrate species. However, it is suggested that the value of rotational grazing with a long rest period as a means of maintaining Siratro productivity could be largely at stocking rates where the pasture is overgrazed in terms of animal performance. Siratro density and seedling regeneration were largely unaffected by treatment and there was a good recovery of Siratro in the heavily grazed treatments during the grazing-free period at the end of the experiment. However, Siratro soil seed reserves declined with increased stocking rate and there was a much greater decline in flowering and seeding. On this basis it is predicted that if grazing treatments had been continued the heavily grazed pastures would eventually have reached the stage where Siratro would not recover with spelling.
