“…Although Zn can be supplied in large amounts without apparent toxic effects [96,97], Zn toxicity may occur and could be mitigated by heavy liming. Despite no Mn additions, Mn availability increased due to urea that acidified the soil [98] and maintained a soil pH below 4.8 [99,100]. The organic fertilizers applied in this study contained Mn, but maintained a soil pH at higher levels, impacting the Mn availability.…”

Long-Term Effects of Animal Manures on Nutrient Recovery and Soil Quality in Acid Typic Hapludalf under No-Till Conditions

No-till farming and manure application are means of storing carbon in soil and increasing soil quality. However, the organic fertilization of no-till soils may sustain subtropical agroecosystems for only a limited period until the soil quality declines. The C, N, P, and other nutrient cycles are perturbed due to the nutrient imbalance in manures and their application on the soil surface, which poses a risk for nutrient dispersion into the environment. Long-term N-based manure application also impacts the apparent nutrient recovery (ANR) by crops and, hence, the crop quality. Our objective was to monitor changes in soil quality and to measure nutrient recovery from N-based organic fertilization in a Brazilian agroecosystem. A long-term experiment was established in May 2004 on Typic Hapludalf soil in Southern Brazil. The experiment comprised two periods: 2004–2009 and 2009–2020. The treatments were unfertilized (control), pig slurry, pig deep litter (swine manure and rice husk), cattle slurry, and mineral fertilizer (urea, triple superphosphate, and K chloride). Grain and cover crops were grown. The maize grain yield and oat biomass were used as indicators of productivity. The application of cattle slurry, pig deep litter, and pig slurry increased the grain production by 20% on average compared to mineral fertilization. Organic manuring increased the soil pH by up to one unit, while urea acidified the soil. The highest crop yields were obtained with pig deep litter, which increased the levels of P, K, Ca, Mg, and C in the soil test. Pig deep litter showed the highest N-ANR for the aboveground part of the plants. The ANRs for P, K, Ca, and Mg were also highest when pig slurry had been applied. The ANR values for the micronutrients varied widely among the organic sources but indicated large marginal offtake gains compared to mineral fertilization. The N-based fertilization with animal manures increased the rate of nutrient uptake by plants but led to an accumulation of nutrients in the soil, threatening the sustainability of the system. Manure applications must be monitored regularly to avoid the accumulation of nutrients that could impair the soil quality and become an environmental problem in the future.

Effect of Soil Temperature on Mineral Element Composition and Morphology of the Potato Plant¹

The influences of two soil temperatures, 5 and 29 C, were studied on potato (Solanum tuberosum) plant growth, tuber yield, and potato plant morphology. The low soil temperature enhanced tuber initiation. Analysis of several minerals showed that the Mn ratio of tops to roots was 0.42 at 5 C and 2.84 at 29 C. At 5 C proliferation and xylem development of roots was restricted, whereas at 29 C the xylem was highly developed. Starch grains were present in the phloem at 5 C but absent at 29 C. This fact suggests that there is a relationship between the assimilate balance and tuber initiation.

Als charakteristisches Mn-OberschuRsymptom wird mit groRer ubereinstimmung bei den meisten Pflanzenarten die Ausbildung von kleinen, scharf begrenzten, braun-schwarzen Punkten beschrieben, die primar am Stengel und den Blattstielen (Eussler, 1958), auf der Unterseite (Morris and Pierre, 1949; Andrees, 1971) oder in der Nahe des Randes der alteren Blattspreiten auftreten. Bei ihren vergleichenden Untersuchungen mit verschiedenen Leguminosenarten konnten Morris and Pierre (1949) bei Soja und SuRklee jedoch diese als typisch beschriebenen Symptome nicht feststellen. Bei diesen Pflanzenarten waren besonders Blattverformungen und gehemmtes Wachstum der Blattspreiten auffallig. Bei Soja beschreiben Parker et al. (1969) bei Mn-UberschuR zwar ebenfalls auf den alteren Blattern verstreute nekrotische Punkte, aber auch sie messen der Verformung jungerer Blatter, die zum Zerreissen der Blattspreite fiihren kann (,,crinkle leaf symptom"), und dem gehemmten Blattspreitenwachstum groRere Bedeutung bei. Diese Ergebnisse von Parker et al. (1969) konnten kurzlich von Heenan and Carter (1975) fur Soja bestatigt werden. Weitgehend identische Symptome (,,crinkle leaf") werden auch haufig bei Baumwolle auf sauren Standorten gefunden und wurden zuerst von Neal( 1937) und Neal und Lovett (1938) beschrieben. Adams und Wear (1957) konnten bei Baumwolle eindeutig nachweisen, daR es sich bei ,,crinkle leaf" um Mn-Toxizitat 1) Dr. W.J.

Es werden insbesondere die jungen, intensiv wachsenden Blatter geschadigt. Als besonders auffalliges Symptom von Mn-UberschuR wird bei bestimmten Versuchsbedingungen auch induzierter Fe-Mangel beschrieben (Sornmers e t al., 1942; Burghard, 1955; Weinstein und Robbins, 1955; Isermann, 1975). In der vorliegenden Arbeit wurde bei Buschbohnen die Entstehung d e r Makround Mikrosymptome von Mn-UberschuR untersucht und versucht, aus d e r Mn-Verteilung im Blattgewebe Ruckschlusse auf die Entstehung der typischen Mn-OberschuRsymptome sowie auf die Art d e r Stoffwechselbeeintrachtigung bei Mn-UberschuR zu ziehen.

Nach dem Vorkeimen wurden die Keimpflanzen zunachst in 1/3 verdiinnte und nach 10 Tagen in voll konzentrierte Nahrlosung(s.u.) gebracht. Dazu wurde je eine Bohnenpflanze in einen Plastikeimer mit 51 standig beliifteter Nahrlosung iibertragen.
