“…In the mixture of Lolium perenne with Medicago x varia T. Martyn, there was the least fibre in the second harvest (257.59 g/kg), and the most in the third (265.62 g/kg). The decrease in fibre content in subsequent harvests of legume-grass mixtures was also recorded by other authors [4,28,31,32]…”

The paper aimed to evaluate fertilizing effects of spent mushroom substrate (SMS) and slurry on dry matter productivity and value of legume-grass mixtures. The experiment was replicated three times, with a split-plot arrangement and plots of 3 m 3 as experimental units. These species were grown as three legume-grass mixtures: M 1-Dactylis glomerata, Lolium perenne, Medicago x varia T. Martyn; M 2-Dactylis glomerata, Medicago x varia T. Martyn; M 3-Lolium perenne, Medicago x varia T. Martyn. The experiment consisted of the following units: control (no fertilization); SMS (30 t/hm 2); slurry (60 m 3 /hm 2) (G); SMS (10 t/hm 2) + slurry (60 m 3 /hm 2); SMS (20 t/hm 2) + slurry (40 m 3 /hm 2); SMS mushroom substrate (30 t/hm 2) + slurry (20 m 3 /hm 2). During each growing season all the mixtures were harvested three times. The fresh matter from each plot was weighted and a sample of 0.6 kg was taken for further analysis. In the experiment the content of both total protein and crude fibre was dependent on the type of fertilizer and on the type of mixture. Forage from the plots with 20 t/hm 2 of mushroom substrate and 40 m 3 /hm 2 of slurry had the best nutritional value, with the highest amount of total protein. The contents of protein and crude fibre in the forage were more favourably affected by slurry than by spent mushroom substrate. Out of the mixtures from all plots, regardless of the type of fertilizer, the mixture consisting of Lolium perenne and Medicago x varia T. Martyn contained the highest content of protein.

“…In that context, the release of phosphatase from roots reflects great microbial activities [65] since plant roots secrete organic compounds that stimulate microbial activity in the rhizosphere hence the enzymatic activity [66,67]. These results are in accord with previous studies [64,68] who observed enhanced enzymatic activities with increased microbial biomass and a positive correlation between, enzymes and soil organic carbon due to activated enzymatic activities by manure and other organic amendments.…”

Aims: To evaluate the effects of phosphate rock and organic inputs on soil organic carbon and acid phosphatase activity. Study Design: The experiment was laid in Randomized Complete Block Design with seven treatments replicated thrice. Place and Duration of Study: The study was conducted at Kigogo Primary school in Meru South Sub-county, Tharaka Nithi County, Kenya. The experiment ran for two consecutive seasons the short rains of 2017 (October to December) and long rains of 2018 (March through June). Methodology: There were seven treatments replicated thrice. The treatments included Tithonia diversifolia, Phosphate rock (PR), Goat manure, Tithonia diversifolia + Phosphate rock, Goat manure + Phosphate rock, Triple superphosphate + Calcium ammonium nitrate and a Control (no soil external inputs). The test crop was maize (Zea mays L.) H516 variety. Soil organic carbon followed modified Walkley and Black oxidation method while acid phosphatase enzyme activity was essayed following the method by Tabatabai and Bremner. Results: Goat manure + phosphate rock, sole phosphate rock and use of goat manure significantly (P= .0001) increased soil organic carbon by 198, 100 and 71% compared to the control. Tithonia diversifolia reported a 3.4-fold increase in soil organic carbon compared to the control in short rains of 2017. Goat manure gave higher soil organic carbon by 135% compared to the control in the long rains of 2018. Goat manure + phosphate rock treatment significantly (P= .0002) increased the phosphatase activity by a difference of 1.12% compared with the control, with 2.14% decreases under TSP+CAN treatment compared to the control. Conclusion: The results showed that integration of phosphate rock and manure could have a far-reaching influence on soil organic carbon and acid phosphatase activity thus could be recommended for improved soil productivity in humic nitisols in similar agro-ecological zones.

“…Lack of competitiveness, seed banks, and limited persistence and dispersal have been obstacles to successful re-establishment of legumes (Bullock et al, 2002;Hu, Liu, Yin, & Song, 2016;Kiehl, Kirmer, Donath, Rasran, & Hölzel, 2010). Successful establishment of forage legumes is also restricted by interspecific competition for limited plant-available P (Crème, Rumpel, Gastal, de la Luz Mora Gil, & Chabbi, 2016;Roscher et al, 2011). Applications of superphosphate is the prevailing approach to reduce P deficiency and provide adequate plantavailable P to seeded legumes in grasslands.…”

Phosphorus and mowing improve native alfalfa establishment, facilitating restoration of grassland productivity and diversity

Seeding legumes into degraded grasslands may effectively replace nitrogen fertilization and restore ecosystem stability by retaining or increasing native plant species diversity while increasing forage production. However, previous research indicated limited legume persistence and potential plant community diversity loss following seeding of legumes into grasslands, constraining successful restoration of degraded grasslands. Our research defined optimal management thresholds for successful legume establishment, reconciling both environmental conservation and production priorities. Large areas of degraded steppe in Inner Mongolia, northeast China, were seeded to either native alfalfa (yellow‐flowered alfalfa: Medicago falcata L.), cultivated alfalfa (purple‐flowered alfalfa: Medicago sativa L.), or left nonseeded (control). Within each seeded area, management treatments (P fertilization or mowing) were assigned to plots in the second year of alfalfa establishment. Our results indicated P amendments and mowing improve native alfalfa establishment, increasing plant productivity while maintaining diverse plant communities, thereby successfully rehabilitating degraded meadow steppe grasslands. However, cultivated alfalfa was not persistent under any management treatment. Alfalfa shoot N and P concentration was linearly related to plant‐available P, indicating P fertilization differentially benefits alfalfa compared with the dominate C3 grass, Leymus chinensis (Trin.) Tzvel. Mowing successfully increased plant species diversity and plant species asynchrony; however, mowing did not alter the temporal stability of plant community productivity, potentially maintaining or enhancing ecosystem stability. Our research showed promise that native alfalfa seeding combined with P fertilization and mowing can restore degraded grasslands to support both forage production and diverse plant communities.
