“…In this study, the soil used was medium so it can be expected that the mineralization process and its effect in releazing the nutrients shall not be so rapid. For this purpose, some authors [8,9,27,28] indicate a positive aspect of organic fertilizers, while other researchers [12,29] point to a negative influence of such amendments on plant quality.…”

“…It is obligatorily described by the macronutrient contents in plant but balanced proportions between the nutrients are important to ensure proper plant development and yield quality. Moreover, it can be generally assumed that the plant nutrient ratios may provide a better index of deficiency of macronutrients than their concentration [8]. In the literature there are very different and broad ranges of nutrient contents given as an optimal and critical levels for crops [30,31].…”

“…Different situation one can notice in relation to the nutrients ratios where values are clearly defined, irrespective of the plants or the fertilization used. Particularly when assessing the fodder nutritive value criteria, correct ratios should be taken into account [10] and the recommended optimal ratios should be as follows: K:Mg = 2-6:1; K:Na = 5:1; Ca:P = 2:1; Ca:Mg = 2-3:1; K:(Ca+Mg) = 1.62-2.2:1; (K+Na):(Ca+Mg) = 1.9-2.1:1 9 [8,22]. Despite clearly defined thresholds for the nutrient ratios, some authors indicate that various plant species (grass, leguminous, herbaceous, crops) markedly differ in terms of their nutrient ratios [8,11,[32][33][34].…”

“…So more the mutual nutrient ratios have specific values or their ranges are constant for plants, regardless of the plant's nutritional needs and differences between species. Moreover, the proportions and relationship between macronutrients in plant biomass can be indicators of vegetation composition and nutrient limitation [8]. However, the assessment of nutrient ratios is less popular.…”

“…However, the assessment of nutrient ratios is less popular. Besides, the authors present nutrient ratios in various ways as in the literature one can find the ionic, mass and even molar ratios of nutrients [8][9][10][11][12]. Macro-and micronutrient contents and their mutual relationships in crops result from, among other things, nutrient availability for plant roots and nutrient antagonisms and synergisms phenomenon.…”

Despite the popularity of concentrated feed, fodder crops are still important, especially in organic livestock farming. However, this type of feed must meet certain criteria, which are often described using correct nutrient ratios. The research investigates the influence of compost and fly ash on quantitative changes in nutrient ratios determined for lupine and oat cultivated on soil slightly contaminated with Cu. A pot experiment was conducted on medium soil. Immobilizing agents (compost and fly ash) were applied at the dose of 40 t per ha. Plant materials were subjected to chemical analyses to assess their macronutrient content and, based on these data, mutual proportions of individual nutrients were calculated as mass ratios of K:Mg, K:Na, Ca:P, Ca:Mg, K:(Ca+Mg) and (K+Na):(Ca+Mg). Changes in ratio values were visualized using statistical tools, i.e., Anova, correlation coefficients and dendrograms. It was found that immobilizing agents constituted a source of the chosen nutrients because their amounts in plants grown on the soil fertilized with either compost or fly ash compost were significantly higher than in the control plants. This phenomenon was especially visible with regard to Ca and Mg for both lupine and oat. It should be emphasized here that the effect of compost or fly ash on the content of Ca and K in plants was comparable. In general, the application of compost contributed to higher values of the analyzed nutrients in both plants. The control and fertilized fly ash plants were characterized by lower values of nutrient ratios. The expected optimal value range of 2–3:1 was determined only for Ca:Mg, which was found in both lupine and oats. The proper values of K:Mg (2–6:1) were found only in the case of fodder plants cultivated on soil amended with compost.

Summary This study aimed at determining the diversity of forage plants utilized for small ruminant feeding in rural and peri-urban sites in Imo state, Nigeria. The survey was carried out at rural and peri-urban sites in Aboh Mbaise and Mbaitoli Local Government Areas (LGAs), respectively. Ten small ruminant farmers were purposively selected from each LGA across the study communities. Data on fodder diversity, proximate composition, and mineral concentration were collected and analyzed using descriptive statistics such as frequency counts, percentages, means, and standard deviation. It was observed that a higher diversity of fodder plants existed at the rural sites compared to the peri-urban sites and 43.4% of the fodder plants were common to both sites. Respondents identified 60.8% of the fodder plants also as food-bearing plants, with 55.6% and 80% of these found at the rural and peri-urban sites, respectively. There were no significant differences (p > 0.05) between the relative proximate or mineral supplies to the animals at the two sites. It was, therefore, concluded that despite the diversity and differences in forage selection at the two sites, the relative nutrient supplies to small ruminants will be similar if the cafeteria system of forage provision practiced at the sites is adhered to.

A b s t r a c t. Legumes are the primary source of plant protein in human food production, but also in pig and poultry feed. In this study, the fodder value of the seeds of three popular species of lupine was evaluated with reference to its variety and the tillage system used to produce it. The plant materials were subjected to chemical analyses to assess their macronutrient (nitrogen -N, phosphorous -P, potassium -K, calcium -Ca, magnesium -Mg and sodium -Na) contents and based on these results, the data ratios of the individual nutrients were calculated as mass ratios of N:P, K:Mg, K:Na, Ca:P, Ca:Mg, K:(Ca+Mg) and (K+Na):(Ca+Mg). Among the calculated nutrient ratios, the highest values were observed for narrow-leaved lupine and the lowest for yellow lupine. No-tillage was conducive to a greater amount of N and Ca being taken up by the narrow-leaved lupine seeds, while conventional cultivation promoted a higher uptake of N, P and Mg by yellow lupine. It was found that the variety grown and tillage system used had little effect on changes in the nutrient ratio values or in nutrient uptake with lupine seed yields. The lupine seeds took up the most nitrogen and the least sodium. The nutrient ratio values used for the fodder value assessment of lupine seeds should be perceived as a useful tool verifying their usefulness and at the same time indicating possible deficiencies and excesses in the amounts of nutrients taken up.K e y w o r d s: nutrient ratio values, variety, tillage, lupine
