“…The use of fully biobased and biodegradable polymers in agriculture field has increased dramatically in recent years throughout the world due to possessing equal performance while not putting pressure on the environment like white pollution [40,41,42,43,44]. For example, numerous degradable polymers including natural ones like starch and synthetic ones like poly(butylene adipate- co -terephtalate) (PBAT), polylactic acid (PLA), poly(3-hydroxybutyrate) (P3HB) and poly(butylene succinate) (PBS) have been applied rather than polyethylene as agriculture mulch [45,46].…”

A novel biobased and biodegradable polyester, i.e., poly(butylene succinate-co-butylene 2-methylsuccinate) (P(BS-BMS)) was synthesized by succinic acid (SA), 2-methylsuccinic acid (MSA), and 1,4-butanediol (BDO) via a typically two-step esterification and polycondensation procedure. The chemical structure and macromolecular weight of obtained copolymers were characterized by 1H NMR, 13C NMR, and GPC. The melting temperature and degree of crystallinity were also studied by DSC, and it was found that the values were gradually decreased with increasing of MSA content, while the thermal stability remained almost unchanged which was tested by TGA. In addition, the biodegradation rate of the P(BS-BMS) copolymers could be controlled by adjusting the ratio of SA and MSA, and such biodegradability could make P(BS-BMS) copolymers avoid microplastic pollution which may be brought to the environment for applications in agricultural field. When we applied P(BS-BMS) copolymers as pesticide carriers which were prepared by premix membrane emulsification (PME) method for controlling Avermectin delivery, an improvement of dispersion and utilization of active ingredient was obviously witnessed. It showed a burst release process first followed by a sustained release of Avermectin for a long period, which had a great potential to be an effective and environmental friendly pesticide-release vehicle.

“…To achieve a more sustainable agriculture, controlled release fertilizers (CRFs), compared to conventional fertilizers, contribute to provide nutrients to the crops throughout their cycle with a single application, allowing the release of the agrochemical at a controlled rate and maintaining its concentration within the optimum limits for a certain period of time, reducing toxicity for seeds. CRF improves the absorption of nutrients by crops through a synchronized release, increasing the fertilizer use efficiency and reducing significantly loss of nutrients …”

“…CRF improves the absorption of nutrients by crops through a synchronized release, increasing the fertilizer use efficiency and reducing significantly loss of nutrients. 1,2,[8][9][10][11][12][13] CRF may be produced by coating conventional fertilizers. 14,15 Polymers such as polyethylene, polystyrene, polyacrylamide, and polysulfone achieve uniformity to the film that covers the fertilizer and good response to sustained release over time.…”

The main purpose of this work is to prepare and characterize films based on chitosan (Q) and hydroxypropyl methylcellulose (HPMC) blends to achieve adequate properties to be used as coating of conventional fertilizers to prolong their availability for crops. The films loaded with KNO 3 as model fertilizer were prepared by casting. Release of fertilizer was studied using sand bed columns. To quantify films durability in soil, their areas were measured in function of time. Results showed that chitosan substantially improved the durability of HPMC, lengthening its permanence in soil 900‰. Relative humidity had influence in mechanical properties. Comparing KNO 3 powder and that loaded in the film, the time of residence in the column was much lower for the powder than the second one: 4 and 56 days, respectively. Chitosan-HPMC film would be promising as polymeric coating for controlled release fertilizers taking into account field conditions.
