THE NEED OF STATE INTERVENTION IN REDUCING PRICE DISPARITY BETWEEN AGRICULTURAL AND INDUSTRIAL PRODUCTS PURCHASED BY AGRICULTURAL PRODUCERS

Written by Maria COJOCARU

The intensification of price disparity between agricultural and industrial products remains one of the unsolved problems of the Republic of Moldova`s agriculture. The differences of price in the farmers’ detriment are also observed in other countries’ economy. In terms of trade liberalization, farmers remain unprotected. The pressure from intermediaries in trade, but also those in the field of food industry, has led to the significant reduction of the share of manufacturer price in the retail price of the final agro food product. Researching this problem, the author believes that the most optimal solution to attenuate the impact of price disparity on the level of agricultural sector`s development is to develop the agricultural infrastructure in complex with state support.

Following the recording and reproducing flooding and draining phenomena that occur naturally in the analysis of the Geraiului Pond, for the development of the solutions (technical and management) for expanding the period of water stagnation in water levels that provides the best conditions for nesting and feeding for the wild waterfowl, especially the red ducks and the pygmy cormorant, the mathematical modeling was use for the ecological reconstruction of this area. Geraiului Pond located at the la confluence of River Olt and the Danube River, in Olt County, between the villages Gârcov and Islaz represents one of the last natural wetlands areas along the river Danube, connected to the natural flood flow of the river. This paper presents mathematical models used to the establishment of technical solutions proposed for reconstruction of Geraiului Pond resulting from the phenomena of flooding and draining modeling of the area.

VARIABILITY OF SOIL SURFACE TEMPERATURE IN THE CÂMPULUNG MUSCEL DEPRESSION (ARGEŞ - ROMANIA)

Published in AgroLife Scientific Journal, Vol. II, Number 1
Written by Cristina - Mihaela CHICHIREZ, Mihai Sorin CÎMPEANU, Doru Ioan MARIN

In the Câmpulung Muscel Depression, the soil surface mean annual temperatureover the past 40 years was 8.5°C, ranging between 7.3°C and 10.4°C. During the year, the temperature of the soil surface was similar to air temperature, except the higher amplitude of the warmest month and the coldest month. The monthly minimum means of the soil was below the monthly minimum means of the air and, except for the months of January and December, themaximum mean was higher than the maximum mean of the air. The absolute minimum temperature of soilsurface was -33.0°C (February 19, 1985), and the absolute maximum was 56.8°C (July 2, 2003). In the Câmpulung Muscel Depression, the last spring frosts and the first autumn frosts were the risk phenomena after May 1 and before October 5. The mean annual number of frost days on the ground was between 14.7 days in the decade 2001-2010 and 165.7 days in the decade 1981-1990.

VARIATION OF THE PARAMETERS OF HARMFUL ACIDITY IN ERODED CINNAMON FOREST SOILS (CHROMIC LUVISOLS) AND ITS RELATION WITH THE SOIL HETEROGENEITY

In this study, the soil acidity is characterized by pH, and content of exchangeable Al3+, H+and Mn2+. It is established the content of exchangeable ions, with neutralizing in respect to harmful acidity effect - exchangeable Ca2+ and Mg2+. On the basis of the results is calculated the degree of saturation of the permanent sorption positions in soil with easily mobile bases V3%. The latter is used as a quality criterion for characterizing the degree of need of liming of soil. The amount of neutralizing lime material is calculated based on the content of easily mobile Al3+, H+and Mn2+ in meq/100g soil. Overcoming the heterogeneity of soil, as regards to the need and rates of liming is done by application of method for geospatialization based on the distribution of sampling points in graticule. The data for eroded cinnamon forest soil show that relatively greatest variation in soil acidity is found in the most eroded areas. In them is more pronounced spatial heterogeneity of soil in respect to easily mobile exchangeable Al3+, H+and Mn2+, while as regards to the contents of easily mobile bases - Ca2+ and Mg2+eroded areas are relatively homogenous. Relatively greatest need of liming, based on the degree of base saturation is observed in average eroded soils, mainly in areas where illuvial clay issettled on the surface and forms relatively deep layer. Application of this ameliorative concept to full neutralization of the harmful Al3+ and part of the H+ and Mn2+ led to calculation of high rates of neutralization meliorants up to 6000 kg/ha.

WHAT ARE THE OPTIONS TO ENSURE A FUTURE SUSTAINABLE NUTRIENT SUPPLY?

Published in AgroLife Scientific Journal, Vol. II, Number 1
Written by Huub LELIEVELD

A billion people are starving or severely undernourished but migration from rural areas to cities will not alleviate this. The situation can, however, be significantly improved by focussing on the actual problems where they occur and address these problems, using the vast amount of knowledge and experience that can be made available and by applying affordable technologies, such as needed for irrigation and reducing post-harvest losses. This cannot be done, however, without teaching the population also how to do this. In addition, smallholder farmers need to learn that cooperation will strengthen their position in negotiations conditions with traders. In areas where food production is scarce, arable land should not be used for breeding of animals for meat as it will be at the expense of growing crops, delivering at least five times less food per surface area. All children should receive at least primary education to ensure that knowledge is retained and will continue to be applied in the future.
