This work aimed to study the effect of humic substances on the availability of P and Zn to wheat depending on the main sorbent surfaces in growth media. \u0000Area of study: Growth chambers of the Higher Technical School of Agricultural Engineering, University of Seville, Spain \u0000Material and methods: To this end, a pot experiment was performed involving three factors: i) HS rates, ii) Zn fertilization, and iii) type of growth medium, calcareous and noncalcareous (siliceous). \u0000Main results: Biomass production and Zn uptake by plants decreased with increasing HS rates. Humic substances decreased zinc uptake more markedly in the siliceous medium. Negative effects of HS can be ascribed to altered crop nutrition and the high aromaticity of HS that can promote phytotoxic effects. The antagonistic effect between P and Zn was less evident in the calcareous medium than in the siliceous medium. This is probably explained by the reduced availability of Zn and the consequent decrease in uptake by plants in the calcareous medium compared to the siliceous medium. These differences observed between both media can be ascribed to different adsorption dynamics depending on the main sorbent surfaces. \u0000Research highlights: The addition of HS, at the intermediate rates studied, had a positive effect on the microbial activity of the rhizosphere in the calcareous medium. Thus, not only crop functioning, but also soil biology, can be affected by the application of HS. This effect can be different depending on the HS rates applied and the type of growth medium.","PeriodicalId":22182,"journal":{"name":"Spanish Journal of Agricultural Research","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41393880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different models were tested to predict the cumulative seedling emergence, and the log logistic model was found to be the best for this A. retroflexus population.

The level of seed dormancy can be reduced during autumn and winter burial in the soil or after a dry storage. Seed dormancy reduction resulted in a lower base temperature for germination/emergence followed by increase of the seedling emergences. Moreover, light in the soil surface and higher fluctuation in temperature at shallower soil depths may stimulate the seed germination and seedling emergence of A. retroflexus. \u0000Research highlights: Total emerged seedlings and emergence pattern are affected by soil depth and the level of dormancy.

Besides, the addition of OM reduced the presence and abundance of potential fungal pathogenic organisms, like Sclerotinia sp. and Plectosphaerella cucumerina. OM addition to conventionally managed greenhouses (CMOM) led to higher crop yields compared to CM greenhouses, resulting in an overall increase of 880 g m-2.

There are few technical materials available focused on hatcheries that address and incorporate practices adopting the welfare level required by civil society. However, about 33% of the production period of a broiler chicken occurs on the hatchery. Recent studies have shown that day-old chick production has points that need to be improved. Technical standards indicate that the process of welfare should begin during egg storage such that the best conditions are provided for embryos prior to incubation. Storage until 28 days at temperatures above 12ºC can kill embryos, while exposure of eggs to 30 ºC until 14 days causes a negative impact under the hatchability. The available results regarding in ovo nutrition show that it should be considered for benefit neonate quality since inoculation of substances such vitamin E (60.4 IU) promote better incubation results. Feeding immediately after hatching is a management for welfare because animals feed-fed soon after hatch perform better up to 35 d. The most criticized point in hatcheries is the slaughter of neonates, for which some strategies are being investigated, including the use of dual-purpose aptitude strains, in ovo sexing by different methodologies, sex inversion and hormonal-based sexing. It is noted that procedures involving bird incubation require greater attention to welfare.
